Żółtaczka
Diagnostyka i diagnoza
Żółtaczka to objaw kliniczny manifestujący się żółtym zabarwieniem skóry, twardówek i błon śluzowych, wynikający z hiperbilirubinemii, gdy stężenie bilirubiny przekracza 2-3 mg/dl (34-51 μmol/l). Wyróżnia się trzy główne typy żółtaczki: przedwątrobową (z przewagą bilirubiny niesprzężonej, bez bilirubiny w moczu, prawidłowymi próbami wątrobowymi), wątrobową (z obecnością bilirubiny sprzężonej w moczu, podwyższonymi enzymami wątrobowymi – ALP, ALT, AST, obniżonym albuminem) oraz pozawątrobową (z przeszkodą w odpływie żółci, obecnością bilirubiny w moczu, bladym stolcem, podwyższonym ALP i aminotransferazami oraz często świądem skóry). Diagnostyka opiera się na szczegółowym wywiadzie, badaniu fizykalnym, oznaczeniu bilirubiny całkowitej i frakcji, próbach wątrobowych, badaniu moczu oraz obrazowaniu (USG, TK, MRCP, ERCP), a w wybranych przypadkach biopsji wątroby. W diagnostyce różnicowej uwzględnia się przyczyny hemolityczne, choroby wątroby, zaburzenia odpływu żółci oraz choroby genetyczne i metaboliczne.

Żółtaczka – definicja i patofizjologia
Żółtaczka (łac. icterus, ang. jaundice) to objaw kliniczny charakteryzujący się żółtym zabarwieniem skóry, twardówek oczu i błon śluzowych spowodowanym podwyższonym stężeniem bilirubiny we krwi (hiperbilirubinemia). Żółta barwa staje się widoczna klinicznie, gdy stężenie bilirubiny we krwi przekracza 2-3 mg/dl (34-51 μmol/l).12 Żółtaczka sama w sobie nie jest chorobą, lecz objawem wskazującym na zaburzenia w metabolizmie bilirubiny, które mogą wynikać z różnych stanów patologicznych dotyczących wątroby, dróg żółciowych lub przemian hemoglobiny.3
Bilirubina jest żółto-pomarańczowym pigmentem powstającym w wyniku rozpadu czerwonych krwinek. W prawidłowych warunkach bilirubina jest transportowana do wątroby, gdzie ulega sprzęganiu (koniugacji), a następnie jest wydalana z żółcią do przewodu pokarmowego. Zaburzenia w którymkolwiek etapie tego procesu mogą prowadzić do hiperbilirubinemii i klinicznie widocznej żółtaczki.45
Istotą różnicowania przyczyn żółtaczki jest ustalenie, czy mamy do czynienia z hiperbilirubinemią niesprzężoną (pośrednią), czy sprzężoną (bezpośrednią). Występowanie bilirubiny w moczu wskazuje na hiperbilirubinemię sprzężoną (żółtaczkę wątrobową lub pozawątrobową), ponieważ tylko bilirubina sprzężona jest rozpuszczalna w wodzie i może być wydalana przez nerki.67
Klasyfikacja żółtaczki
Ze względu na mechanizm powstawania oraz lokalizację patologii, żółtaczkę można podzielić na trzy główne typy:89
Żółtaczka przedwątrobowa (hemolityczna)
Ten typ żółtaczki charakteryzuje się nadmiernym rozpadem czerwonych krwinek, co prowadzi do zwiększonej produkcji bilirubiny niesprzężonej, przekraczającej zdolność wątroby do jej przetwarzania.10 W żółtaczce przedwątrobowej stwierdza się:11
- Brak bilirubiny w moczu
- Podwyższone stężenie bilirubiny niesprzężonej (pośredniej) we krwi
- Prawidłowe lub obniżone stężenie hemoglobiny
- Prawidłowe próby wątrobowe
Żółtaczka wątrobowa (hepatocellularna)
Żółtaczka wątrobowa jest spowodowana dysfunkcją samych hepatocytów, co prowadzi do upośledzenia procesu sprzęgania bilirubiny w wątrobie.14 Charakteryzuje się:15
- Obecnością bilirubiny sprzężonej w moczu
- Obniżonym stężeniem albumin w surowicy krwi
- Podwyższonym stężeniem globulin
- Ciemną barwą moczu i prawidłowym lub bladym zabarwieniem stolca
- Podwyższonymi wartościami enzymów: fosfatazy alkalicznej (ALP), aminotransferazy alaninowej (ALT) i aminotransferazy asparaginianowej (AST)
Żółtaczka pozawątrobowa (cholestatyczna)
Żółtaczka pozawątrobowa jest spowodowana przeszkodą w odpływie żółci, co uniemożliwia wydalanie bilirubiny sprzężonej z organizmu.17 Charakteryzuje się:18
- Podwyższonym stężeniem bilirubiny sprzężonej we krwi
- Obecnością bilirubiny w moczu (ciemny mocz)
- Bladym zabarwieniem stolca
- Podwyższonym stężeniem fosfatazy alkalicznej i aminotransferaz
- Często towarzyszącym świądem skóry
Podejście diagnostyczne w żółtaczce
Diagnostyka żółtaczki powinna być prowadzona w sposób systematyczny, zaczynając od starannego wywiadu i badania przedmiotowego, następnie wykonania badań laboratoryjnych, a w razie potrzeby również badań obrazowych. Wczesne rozpoznanie przyczyny żółtaczki jest kluczowe dla wdrożenia odpowiedniego leczenia.2021
Wywiad lekarski
Dokładny wywiad jest niezbędnym pierwszym krokiem w diagnostyce żółtaczki. Należy zwrócić uwagę na:22
- Czas wystąpienia objawów (żółtaczka pojawiająca się w ciągu pierwszych 24 godzin od urodzenia jest zwykle patologiczna)
- Zażywane leki i używki (alkohol, narkotyki)
- Narażenie na substancje toksyczne
- Czynniki ryzyka wirusowego zapalenia wątroby (podróże, niebezpieczne zachowania seksualne)
- Status HIV
- Występowanie w rodzinie chorób dziedzicznych lub zaburzeń hemolitycznych
- Przebyte operacje na drogach żółciowych lub wątrobie
- Obecność innych objawów: ból brzucha, gorączka, utrata masy ciała, świąd skóry
Badanie przedmiotowe
Badanie fizykalne jest kluczowym elementem diagnozowania żółtaczki, pozwalającym na wstępne określenie przyczyny i ciężkości schorzenia.25 Podczas badania należy zwrócić uwagę na:26
- Obecność objawów ciężkiej choroby (gorączka, bardzo niskie ciśnienie krwi, przyspieszony rytm serca)
- Ocenę zabarwienia skóry i twardówek (żółtaczka rozprzestrzenia się zazwyczaj w kierunku od głowy do stóp)
- Objawy wskazujące na znaczne upośledzenie funkcji wątroby (skłonność do siniaków, wysypka w postaci drobnych kropek lub plam, zaburzenia funkcji umysłowych)
- Badanie brzucha: ocena wielkości i bolesności wątroby oraz obecności palpacyjnej masy
- Ocena obecności wodobrzusza i splenomegalii
- Ocena zabarwienia moczu i stolca
Badania laboratoryjne
Badania laboratoryjne są niezbędne do potwierdzenia żółtaczki, określenia jej typu i nasilenia oraz ukierunkowania dalszej diagnostyki.29 Do podstawowych badań należą:
Oznaczenie bilirubiny
Pierwsze badanie diagnostyczne w żółtaczce to oznaczenie stężenia bilirubiny całkowitej oraz jej frakcji sprzężonej (bezpośredniej) i niesprzężonej (pośredniej) w surowicy krwi.30 Dominujący typ hiperbilirubinemii pomaga w ustaleniu przyczyny żółtaczki:31
- Przewaga bilirubiny niesprzężonej sugeruje hemolizę lub zaburzenia wychwytu/sprzęgania bilirubiny
- Przewaga bilirubiny sprzężonej wskazuje na uszkodzenie hepatocytów lub przeszkodę w odpływie żółci
Próby wątrobowe
Badania funkcji wątroby dostarczają cennych informacji o stanie hepatocytów i dróg żółciowych:33
- Aminotransferazy (ALT, AST) – podwyższone wartości wskazują na uszkodzenie komórek wątrobowych
- Fosfataza alkaliczna (ALP) i gamma-glutamylotranspeptydaza (GGTP) – znaczny wzrost sugeruje cholestazę
- Albumina i białko całkowite – obniżone wartości mogą świadczyć o przewlekłym uszkodzeniu wątroby
- Czas protrombinowy i INR – przedłużone wartości wskazują na upośledzenie funkcji syntetycznej wątroby
Wzór wzrostu enzymów wątrobowych może sugerować rodzaj patologii:36
- Podejrzenie uszkodzenia hepatokomórkowego – gdy aminotransferazy są >500 U/L, a wzrost fosfatazy alkalicznej <3 razy powyżej normy
- Podejrzenie cholestazy – gdy aminotransferazy są 3 razy powyżej normy
Dodatkowe badania krwi
W zależności od wstępnych wyników i podejrzewanej przyczyny, mogą być konieczne dalsze badania laboratoryjne:38
- Morfologia krwi obwodowej – może wskazywać na anemię hemolityczną, proces zapalny lub zakażenie
- Badania serologiczne w kierunku wirusowych zapaleń wątroby (panel wirusologiczny)
- Badania immunologiczne (przeciwciała przeciwjądrowe, przeciwciała przeciwko mięśniom gładkim, przeciwciała przeciwko mikrosomom wątroby i nerek) – przy podejrzeniu chorób autoimmunologicznych
- Badania biochemiczne moczu – obecność bilirubiny w moczu wskazuje na hiperbilirubinemię sprzężoną
Badania obrazowe
Badania obrazowe odgrywają kluczową rolę w różnicowaniu żółtaczki wątrobowej od pozawątrobowej oraz w identyfikacji konkretnej przyczyny.41 Do najważniejszych metod należą:
Ultrasonografia jamy brzusznej
Badanie ultrasonograficzne (USG) jest zazwyczaj pierwszym badaniem obrazowym wykonywanym u pacjentów z żółtaczką.42 Jest to badanie nieinwazyjne, tanie i szeroko dostępne, które pozwala na ocenę:43
- Wielkości i echogeniczności wątroby
- Poszerzenia wewnątrz- i zewnątrzwątrobowych dróg żółciowych
- Obecności kamieni żółciowych
- Zmian ogniskowych w wątrobie
- Stanu pęcherzyka żółciowego i trzustki
Tomografia komputerowa (TK)
Tomografia komputerowa jest bardziej czułą metodą obrazowania, szczególnie przydatną w diagnostyce nowotworów wątroby, dróg żółciowych i trzustki.45 Badanie to umożliwia dokładniejszą ocenę miąższu wątroby, dróg żółciowych oraz sąsiadujących struktur.46
Rezonans magnetyczny (MRI) i cholangiopankreatografia rezonansu magnetycznego (MRCP)
MRCP jest nieinwazyjną metodą obrazowania dróg żółciowych i przewodu trzustkowego, szczególnie użyteczną w diagnostyce zwężeń i niedrożności dróg żółciowych.47 Badanie to może być alternatywą dla endoskopowej cholangiopankreatografii wstecznej (ERCP) w diagnostyce patologii dróg żółciowych.48
Endoskopowa cholangiopankreatografia wsteczna (ERCP)
ERCP jest inwazyjną metodą diagnostyczno-terapeutyczną, która umożliwia bezpośrednią wizualizację dróg żółciowych i przewodu trzustkowego poprzez wprowadzenie endoskopu do dwunastnicy i wstrzyknięcie kontrastu do dróg żółciowych.49 ERCP pozwala nie tylko na diagnostykę, ale również na wykonanie zabiegów terapeutycznych, takich jak usunięcie kamieni żółciowych, rozszerzenie zwężeń czy założenie stentu.50
Endoskopowa ultrasonografia (EUS)
Endoskopowa ultrasonografia łączy endoskopię z badaniem ultrasonograficznym, umożliwiając dokładną ocenę dróg żółciowych, trzustki i okolicznych struktur. Jest szczególnie przydatna w diagnostyce małych zmian w trzustce i dystalnej części dróg żółciowych.51
Biopsja wątroby
Biopsja wątroby jest inwazyjnym badaniem diagnostycznym, które pozwala na bezpośrednią ocenę tkanki wątrobowej.52 Jest zarezerwowana dla przypadków, w których diagnoza pozostaje niejasna po wykonaniu badań nieinwazyjnych, a wyniki mogą wpłynąć na decyzje terapeutyczne i rokowanie.53
Biopsja wątroby może być wykonana przezskórnie pod kontrolą ultrasonografii lub tomografii komputerowej, przez żyłę szyjną (biopsja przezżylna) lub podczas zabiegu laparoskopowego.54 Wskazania do biopsji wątroby obejmują:55
- Ocenę zaawansowania przewlekłych chorób wątroby
- Różnicowanie chorób cholestatycznych
- Diagnostykę chorób metabolicznych wątroby
- Diagnostykę zmian ogniskowych w wątrobie o niejasnym charakterze
Szczególne aspekty diagnostyki żółtaczki
Diagnostyka żółtaczki u noworodków
Żółtaczka noworodków występuje u około 60% donoszonych i 80% wcześniaków w pierwszym tygodniu życia.56 Diagnostyka obejmuje:57
- Ocenę wizualną – żółtaczka rozprzestrzenia się zazwyczaj od głowy w dół; zajęcie dłoni i stóp sugeruje ciężką hiperbilirubinemię
- Pomiar stężenia bilirubiny – za pomocą bilirubinometru przezskórnego (nieinwazyjna metoda) lub poprzez badanie krwi
- Dodatkowe badania krwi w przypadku przedłużającej się żółtaczki (>2 tygodni) lub wymagającej leczenia
Szczególnej uwagi wymaga żółtaczka pojawiająca się w pierwszych 24 godzinach życia, gdyż jest zwykle objawem patologii wymagającej natychmiastowej interwencji.59 Przy przedłużającej się żółtaczce noworodkowej należy rozważyć:60
- Badanie krwi w kierunku konfliktu serologicznego (test Coombsa)
- Morfologię krwi, retikulocyty, rozmaz krwi obwodowej
- Oznaczenie grup krwi
- Badanie w kierunku niedoboru dehydrogenazy glukozo-6-fosforanowej (G6PD)
- Próby wątrobowe
- Badanie moczu na obecność substancji redukujących
- Badanie ultrasonograficzne jamy brzusznej
Diagnostyka żółtaczki u dorosłych

- Panel wirusologiczny (wirusowe zapalenia wątroby A, B, C)
- Badania autoimmunologiczne (przeciwciała przeciwjądrowe, przeciwko mięśniom gładkim, przeciwko mikrosomom wątroby i nerek)
- Tomografia komputerowa lub rezonans magnetyczny z MRCP
- ERCP – w przypadku podejrzenia niedrożności dróg żółciowych
- Biopsja wątroby – gdy diagnoza pozostaje niejasna
Kiedy konieczna jest pilna diagnostyka?
Niektóre objawy towarzyszące żółtaczce wymagają natychmiastowej diagnostyki i interwencji:67
- Nasilony ból i tkliwość brzucha
- Zaburzenia świadomości
- Krwawienie z przewodu pokarmowego
- Wysoka gorączka
- Wybroczyny, podbiegnięcia krwawe lub plamica
- Żółtaczka u kobiet w ciąży
Pilnej hospitalizacji wymagają pacjenci z żółtaczką i encefalopatią wątrobową oraz podejrzeniem wstępującego zapalenia dróg żółciowych (triada Charcota: gorączka, żółtaczka, ból w prawym podżebrzu).70
Diagnostyka różnicowa żółtaczki
Diagnostyka różnicowa żółtaczki powinna uwzględniać szeroki wachlarz patologii w zależności od typu hiperbilirubinemii.71
Hiperbilirubinemia niesprzężona
Przyczyny żółtaczki z przewagą bilirubiny niesprzężonej obejmują:72
- Nadmierny rozpad czerwonych krwinek (hemoliza) – niedokrwistości hemolityczne autoimmunologiczne i nieimmunologiczne
- Wchłanianie dużych krwiaków
- Zespół Gilberta – łagodne zaburzenie genetyczne polegające na zmniejszonej aktywności UDP-glukuronylotransferazy
- Zespół Criglera-Najjara – rzadkie zaburzenie genetyczne z całkowitym lub częściowym brakiem UDP-glukuronylotransferazy
- Niedoczynność tarczycy
- Żółtaczka fizjologiczna u noworodków
- Żółtaczka z pokarmem matki

- #1 Jaundice – Hepatic and Biliary Disorders – Merck Manual Professional Editionhttps://www.merckmanuals.com/professional/hepatic-and-biliary-disorders/approach-to-the-patient-with-liver-disease/jaundice
Jaundice is a yellowish discoloration of the skin and mucous membranes caused by hyperbilirubinemia. Jaundice becomes visible when the bilirubin level is about 2 to 3 mg/dL (34 to 51 micromol/L). […] Hyperbilirubinemia may involve predominantly unconjugated or conjugated bilirubin. […] Outcome is determined primarily by the cause of jaundice and the presence and severity of hepatic dysfunction. Hepatic dysfunction can result in coagulopathy, encephalopathy, and portal hypertension (which can lead to gastrointestinal bleeding). […] Although hyperbilirubinemia can be classified as predominantly unconjugated or conjugated, many hepatobiliary disorders cause both forms. […] Many conditions can cause jaundice, but the most common causes overall are inflammatory hepatitis (viral hepatitis, autoimmune hepatitis, toxic hepatic injury), alcohol-related liver disease, and biliary obstruction.
- #2 Assessment of jaundice – Differential diagnosis of symptoms | BMJ Best Practicehttps://bestpractice.bmj.com/topics/en-gb/511
Jaundice (icterus) is the result of accumulation of bilirubin in the bloodstream and subsequent deposition in the skin, sclera, and mucous membranes. The normal range for total bilirubin is 3.4 to 20.0 micromol/L (0.2 to 1.2 mg/dL). Jaundice may not be clinically evident until serum levels 51 micromol/L (3 mg/dL). […] Jaundice might result from increased bilirubin production (prehepatic), diseases that impair hepatocyte function (hepatocellular), or obstruction of the biliary system (cholestatic). […] After a focused history and examination, evaluation of the liver with full blood count, serum liver function tests, and ultrasound is appropriate for most patients. Further imaging and laboratory tests depend on the likely diagnosis.
- #3 Azthena logo with the word Azthenahttps://www.news-medical.net/health/Jaundice-Diagnosis.aspx
Jaundice is a symptom of an underlying condition rather than a disease in itself. Jaundice is caused by an accumulation of a yellowgreen substance called bilirubin in the tissues of the body, which causes a yellowing of the skin, eyes and mucous membranes. […] Jaundice is categorized into three different forms, depending on what the underlying cause of the bilirubin build-up is. The different types of jaundice are described below. […] For each type of jaundice, the clinical features of the disease are different, as outlined below. […] Pre-hepatic jaundice There is no bilirubin present in the urine and there is an increase in the level of unconjugated bilirubin in the blood. […] Hepatocellular jaundice Conjugated bilirubin is present in the urine. The plasma albumin level is reduced, but globulins are raised in response to an increase in antibodies. The urine is dark-colored and the stools are either normal or pale. Enzymes alkaline phosphatase, alanine transferase and aspartate transferase are all raised. […] Post hepatic or obstructive jaundice The blood level of conjugated bilirubin is raised; the urine is dark-colored and the stools are pale. Alkaline phosphatase, alanine transferase and aspartate transferase levels are all raised.
- #4 Adult Jaundice: What It Is, Symptoms, Causes & Treatmenthttps://my.clevelandclinic.org/health/symptoms/15367-adult-jaundice
Jaundice (hyperbilirubinemia) is when your skin, sclera (whites of your eyes) and mucous membranes turn yellow. Jaundice occurs when your liver is unable to process bilirubin (a yellow substance made when red blood cells break down) in your blood. This can either be caused by too much red blood cell breakdown or liver injury. […] Jaundice can result from a problem in any of the three phases of bilirubin: […] Your provider can tell if you have jaundice by measuring the bilirubin levels in your blood and seeing whether its the type of bilirubin related to red blood cell breakdown (unconjugated) or liver injury (conjugated). […] Your healthcare provider will also examine you to decide your livers size and tenderness. They may use imaging (ultrasound and CT scanning) and liver biopsy (taking a tissue sample of your liver) to better understand whats causing your liver injury. […] Theres no specific treatment for jaundice. But your provider can treat the cause and the jaundice should improve. […] A healthcare provider should evaluate jaundice. Its a sign that somethings not right with your liver. If you notice signs of jaundice, call your healthcare provider.

Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. […] The prevalence of jaundice in adults is rare, while jaundice in babies is common, with an estimated 80% affected during their first week of life. […] Normal levels of bilirubin in blood are below 1.0 mg/dl (17 mol/L), while levels over 23 mg/dl (3451 mol/L) typically result in jaundice. […] High blood bilirubin is divided into two types: unconjugated and conjugated bilirubin. […] Causes of jaundice vary from relatively benign to potentially fatal. […] High unconjugated bilirubin may be due to excess red blood cell breakdown, large bruises, genetic conditions such as Gilbert’s syndrome, not eating for a prolonged period of time, newborn jaundice, or thyroid problems.

Jaundice is a symptom of an underlying condition rather than a disease in itself. Jaundice is caused by an accumulation of a yellowgreen substance called bilirubin in the tissues of the body, which causes a yellowing of the skin, eyes and mucous membranes. […] Jaundice is categorized into three different forms, depending on what the underlying cause of the bilirubin build-up is. The different types of jaundice are described below. […] For each type of jaundice, the clinical features of the disease are different, as outlined below. […] Pre-hepatic jaundice There is no bilirubin present in the urine and there is an increase in the level of unconjugated bilirubin in the blood. […] Hepatocellular jaundice Conjugated bilirubin is present in the urine. The plasma albumin level is reduced, but globulins are raised in response to an increase in antibodies. The urine is dark-colored and the stools are either normal or pale. Enzymes alkaline phosphatase, alanine transferase and aspartate transferase are all raised. […] Post hepatic or obstructive jaundice The blood level of conjugated bilirubin is raised; the urine is dark-colored and the stools are pale.

Jaundice in adults can be an indicator of significant underlying disease. It is caused by elevated serum bilirubin levels in the unconjugated or conjugated form. The evaluation of jaundice relies on the history and physical examination. The initial laboratory evaluation should include fractionated bilirubin, a complete blood count, alanine transaminase, aspartate transaminase, alkaline phosphatase, -glutamyltransferase, prothrombin time and/or international normalized ratio, albumin, and protein. Imaging with ultrasonography or computed tomography can differentiate between extrahepatic obstructive and intrahepatic parenchymal disorders. […] A retrospective study of more than 700 individuals found that most cases (55%) of acute jaundice in adults are caused by intrahepatic disorders, including viral hepatitis, alcoholic liver disease, and drug-induced liver injury. The remaining 45% of acute jaundice cases are extrahepatic and include gallstone disease, hemolysis, and malignancy.

Jaundice is a yellow color of the skin, mucus membranes, or eyes. The yellow coloring comes from bilirubin, a byproduct of old red blood cells. Obstructive jaundice is a specific type of jaundice, where symptoms develop due to a narrowed or blocked bile duct or pancreatic duct, preventing the normal drainage of bile from the bloodstream into the intestines. […] Specialists at the Center for Advanced Digestive Care (CADC) at NewYork-Presbyterian/Weill Cornell Medical Center are experienced in diagnosing and treating the causes of obstructive jaundice. Our Center for Liver Disease and Transplantation uses a multidisciplinary approach and tailor treatment to the needs of each patient. […] Obstructive jaundice, also known as cholestatic jaundice, is a condition characterized by the obstruction of bile flow from the liver to the small intestine. This obstruction can occur due to various reasons, such as gallstones, tumors, or inflammation of the bile ducts. Recognizing the symptoms of obstructive jaundice is crucial for timely diagnosis and treatment.

Jaundice is the yellow color of skin and mucous membranes due to accumulation of bile pigments in blood and their deposition in body tissues. Jaundice must be distinguished from yellow or green skin color resulting from carotenemia or quinacrine ingestion. The majority of jaundiced patients may be diagnosed by careful and meticulous history and physical examination. Assessment of constitutional symptoms often provides the first clue to the mechanism of jaundice. Symptoms associated with jaundice often provide a diagnosis. The jaundiced patient requires thorough documentation of all recent drug and toxin exposures. Potential contact with hepatitis viruses and other infectious agents should also be determined. Surgical history, whether recent or remote may be implicated in the cause of jaundice. Other systemic conditions may have complications related to the liver. A family history of jaundice, liver disease, or anemia should be sought. In most instances, physical examination of the jaundiced patient confirms a diagnosis suspected by history or provides diagnostic proof in its own right. Examination of the skin may reveal bruising resulting from disturbed blood coagulation mechanisms. Auscultation over the liver should be performed prior to manual manipulation of the area. Palpation of the liver is the single most crucial step in evaluation of the jaundiced patient. Splenomegaly is frequently found in the jaundiced patient, although its specific etiology is variable. Ascites in the jaundiced patient is an ominous sign, usually signifying severely decompensated cirrhosis with portal hypertension or malignancy. Dark urine resembling tea, which develops a green foam on shaking, is caused by bile pigment. Laboratory tests usually serve to confirm the pathophysiology of jaundice. The complete blood count may provide evidence for hemolysis by demonstrating anemia in a patient without blood loss. Liver function tests are nonspecific indicators of liver disease. Normal serum bilirubin concentration is usually no greater than 1.5 mg/dl and is composed primarily of the unconjugated form. Serum alkaline phosphatase is often elevated to at least three times the upper limit of normal in patients with jaundice due to intra- or extrahepatic obstruction. Transaminase elevations are common in both hepatocellular and obstructive jaundice. Prothrombin precursor is a protein manufactured by the liver whose full expression of activity in coagulation relies on a vitamin K-dependent carboxylase. Albumin is synthesized in the liver. Serologic assays for hepatitis A and B viruses should be performed in cases of acutely developing jaundice. Imaging investigation should start with a chest x-ray and plain film of the abdomen. Abdominal sonography is a valuable screening test in the jaundiced patient. Computerized tomography has the advantage of surveying the entire abdomen as well as the hepatobiliary-pancreatic axis. Until recently, hepatobiliary scintigraphy had little to contribute to the differential diagnosis of jaundice. Percutaneous transhepatic cholangiography involves passage of a thin needle into the liver under fluoroscopic guidance and injection of contrast into the biliary tree. Endoscopic retrograde cholangiopancreatography is performed by passing a flexible fiberoptic endoscope into the patient’s duodenum. The most important question to answer in the evaluation of any jaundiced patient is, „Will this patient require surgery to relieve biliary obstruction?”

Jaundice is obvious, but identifying its cause requires a doctor’s examination, blood tests, and sometimes other tests. […] If people have any warning signs, they should see a doctor as soon as possible. People with no warning signs should see a doctor within a few days. […] Doctors typically measure bilirubin levels in the blood and do blood tests to determine how well the liver is functioning and whether it is damaged (tests of liver function) and to assess the blood’s ability to clot. […] Tests include the following: Blood tests to evaluate how well the liver is functioning and whether it is damaged (liver tests). […] Doctors first ask questions about the person’s symptoms and medical history. Doctors then do a physical examination.

In adults, common causes of cholestatic jaundice comprise biliary obstruction by stones, strictures, and malignancy. […] For the jaundiced patient, careful and detailed history taking and examination should always be performed to elicit any red-flag symptoms and identify risk factors for liver disease, including alcohol misuse. […] Some cases of jaundice can be managed safely in primary care. However, emergency admission should be considered if the patient is systemically unwell in conjunction with jaundice, and any patient with marked derangement of liver blood tests, evidence of liver synthetic failure such as reduced albumin or prolonged prothrombin time, or clinical symptoms suspicious of malignancy or other serious underlying condition should be urgently referred. […] In neonates, a referral for urgent medical review should be made for babies with suspected or obvious jaundice in the first 24 hours of life to exclude pathological causes of jaundice. […] Babies with prolonged jaundice should be investigated in accordance with NICE guidance, and all babies with a conjugated bilirubin level greater than 25 micromol/l should be referred urgently to secondary care to assess for severe underlying liver disease.

[…] This topic will provide an overview of the diagnostic approach to adults with jaundice or asymptomatic hyperbilirubinemia. The causes of jaundice and asymptomatic hyperbilirubinemia, detailed discussions of the specific testing used, and the evaluation of patients with other liver test abnormalities are discussed elsewhere. […] For clinical purposes, serum bilirubin is fractionated to classify hyperbilirubinemia into one of two major categories: Unconjugated hyperbilirubinemia is characterized by plasma elevation of predominantly unconjugated (indirect) bilirubin. This may be due to the overproduction of bilirubin, impaired bilirubin uptake by the liver, or abnormalities of bilirubin conjugation. […] In patients with conjugated hyperbilirubinemia, both unconjugated and conjugated (direct) bilirubin are elevated. This may be due to hepatocellular disease, impaired canalicular excretion of bilirubin, or biliary obstruction.

The major feature noted on the serum biochemistry profile when increased red blood cell destruction is the cause of jaundice is an increase in the serum bilirubin concentrations (hyperbilirubinemia). […] A urinalysis confirms the presence of hyperbilirubinemia by documenting increased amounts of bilirubin in the urine. […] Occasionally, immune-mediated destruction of red blood cells is suspected but cannot be definitively confirmed with the above screening tests. […] The CBC may indicate the presence of inflammation or infection within the liver and/or gall bladder by an increased white blood cell count. […] Although changes in the biochemistry profile may support the diagnosis of liver disease, they rarely indicate the exact cause. […] Destruction of individual liver cells (hepatocytes) is indicated by increases in the liver enzymes ALT (alanine aminotransferase) and AST (aspartate transaminase).

Jaundice, also referred to as hyperbilirubinemia, is characterised as a yellow discolouration of bodily tissue brought on by the buildup of too much bilirubin. Bilirubin deposition only occurs when there is an excess of bilirubin, which suggests increased production or impaired excretion. […] The most crucial laboratory test to perform is a liver function test after taking a comprehensive medical history and performing physical exams. […] Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyltransferase, serum albumin, protein, and bilirubin levels are measured during liver function exams. […] If the AST, ALT, and ALP values are normal, liver or bile duct damage is not the cause of the jaundice. Pre-hepatic conditions such as blood disorders, inherited liver conjugation disorders, or defects in hepatic excretion must be the reason. (Rotor, Dubin-Johnson).

The challenge for the clinician is to establish the cause of jaundice and, as part of this, decide whether jaundice represents a benign and self-limiting condition or a serious underlying illness. […] The patients clinical presentation is suggestive of acute hepatitis. […] Although jaundice in neonates is common and normal, especially in breast-fed babies, both early jaundice (within the first week of life) and prolonged jaundice (jaundice persisting beyond the first 14 days) may be indicators of an underlying medical condition. […] In a child with prolonged jaundice, the clinician must always consider biliary atresia as a possible cause, and early diagnosis of this condition is crucial. […] Jaundice with predominantly raised ALP and only moderately raised ALT suggests a cholestatic or post-hepatic picture, in which the biliary tree external to the liver is blocked.

[…] To get more information, your doctor will likely order blood tests to measure bilirubin and cholesterol levels and get a complete blood count (CBC). If you have jaundice, your level of bilirubin will be high. Your doctor may order other tests to find the cause of your jaundice and how severe it is, including: […] A hepatitis panel, which is a blood test that shows if you have, or have had, hepatitis. It tests for hepatitis A, hepatitis B, and hepatitis C. If there are no hepatitis antibodies in your blood, it means you don’t have the condition, or you had it in the past, but your body has cleared it. […] Tests to check enzyme levels in the liver to see how well it is functioning. If enzyme levels are higher or lower than normal, it can mean you have disease or damage to the liver or bile ducts. […] Imaging, like a CT scan, ultrasound, or magnetic resonance cholangiopancreatography, a type of MRI that checks for blocked ducts near the gallbladder […] A liver biopsy, to show if you have damage to, or disease in, your liver. During the test, a small piece of your liver is removed either with a needle inserted into the belly to the liver, through a vein in your neck, or through a cut in your belly. […] Prothrombin time, which measures how long it takes for blood plasma to clot.

- #45 Jaundice – Clinical Methods – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK413/
Jaundice is the yellow color of skin and mucous membranes due to accumulation of bile pigments in blood and their deposition in body tissues. Jaundice must be distinguished from yellow or green skin color resulting from carotenemia or quinacrine ingestion. The majority of jaundiced patients may be diagnosed by careful and meticulous history and physical examination. Assessment of constitutional symptoms often provides the first clue to the mechanism of jaundice. Symptoms associated with jaundice often provide a diagnosis. The jaundiced patient requires thorough documentation of all recent drug and toxin exposures. Potential contact with hepatitis viruses and other infectious agents should also be determined. Surgical history, whether recent or remote may be implicated in the cause of jaundice. Other systemic conditions may have complications related to the liver. A family history of jaundice, liver disease, or anemia should be sought. In most instances, physical examination of the jaundiced patient confirms a diagnosis suspected by history or provides diagnostic proof in its own right. Examination of the skin may reveal bruising resulting from disturbed blood coagulation mechanisms. Auscultation over the liver should be performed prior to manual manipulation of the area. Palpation of the liver is the single most crucial step in evaluation of the jaundiced patient. Splenomegaly is frequently found in the jaundiced patient, although its specific etiology is variable. Ascites in the jaundiced patient is an ominous sign, usually signifying severely decompensated cirrhosis with portal hypertension or malignancy. Dark urine resembling tea, which develops a green foam on shaking, is caused by bile pigment. Laboratory tests usually serve to confirm the pathophysiology of jaundice. The complete blood count may provide evidence for hemolysis by demonstrating anemia in a patient without blood loss. Liver function tests are nonspecific indicators of liver disease. Normal serum bilirubin concentration is usually no greater than 1.5 mg/dl and is composed primarily of the unconjugated form. Serum alkaline phosphatase is often elevated to at least three times the upper limit of normal in patients with jaundice due to intra- or extrahepatic obstruction. Transaminase elevations are common in both hepatocellular and obstructive jaundice. Prothrombin precursor is a protein manufactured by the liver whose full expression of activity in coagulation relies on a vitamin K-dependent carboxylase. Albumin is synthesized in the liver. Serologic assays for hepatitis A and B viruses should be performed in cases of acutely developing jaundice. Imaging investigation should start with a chest x-ray and plain film of the abdomen. Abdominal sonography is a valuable screening test in the jaundiced patient. Computerized tomography has the advantage of surveying the entire abdomen as well as the hepatobiliary-pancreatic axis. Until recently, hepatobiliary scintigraphy had little to contribute to the differential diagnosis of jaundice. Percutaneous transhepatic cholangiography involves passage of a thin needle into the liver under fluoroscopic guidance and injection of contrast into the biliary tree. Endoscopic retrograde cholangiopancreatography is performed by passing a flexible fiberoptic endoscope into the patient’s duodenum. The most important question to answer in the evaluation of any jaundiced patient is, „Will this patient require surgery to relieve biliary obstruction?”

- #62 Jaundice in the Adult Patient | AAFPhttps://www.aafp.org/pubs/afp/issues/2004/0115/p299.html
Jaundice in an adult patient can be caused by a wide variety of benign or life-threatening disorders. Organizing the differential diagnosis by prehepatic, intrahepatic, and posthepatic causes may help make the work-up more manageable. Prehepatic causes of jaundice include hemolysis and hematoma resorption, which lead to elevated levels of unconjugated (indirect) bilirubin. Intrahepatic disorders can lead to unconjugated or conjugated hyperbilirubinemia. The conjugated (direct) bilirubin level is often elevated by alcohol, infectious hepatitis, drug reactions, and autoimmune disorders. Posthepatic disorders also can cause conjugated hyperbilirubinemia. Gallstone formation is the most common and benign posthepatic process that causes jaundice; however, the differential diagnosis also includes serious conditions such as biliary tract infection, pancreatitis, and malignancies. The laboratory work-up should begin with a urine test for bilirubin, which indicates that conjugated hyperbilirubinemia is present. If the complete blood count and initial tests for liver function and infectious hepatitis are unrevealing, the work-up typically proceeds to abdominal imaging by ultrasonography or computed tomographic scanning. In a few instances, more invasive procedures such as cholangiography or liver biopsy may be needed to arrive at a diagnosis.
- #63 Jaundice in the Adult Patient | AAFPhttps://www.aafp.org/pubs/afp/issues/2004/0115/p299.html
Jaundice is not a common presenting complaint in adults. When present, it may indicate a serious problem. This article discusses the evaluation of the adult patient with jaundice. A systematic approach is warranted to clarify the cause quickly so that treatment can begin as soon as possible. […] The initial work-up of the patient with jaundice depends on whether the hyperbilirubinemia is conjugated (direct) or unconjugated (indirect). A urinalysis that is positive for bilirubin indicates the presence of conjugated bilirubinemia. Conjugated bilirubin is water soluble and therefore able to be excreted in urine. The findings of urinalysis should be confirmed by measurements of the serum total and direct bilirubin levels. […] First-line serum testing in a patient presenting with jaundice should include a complete blood count (CBC) and determination of bilirubin (total and direct fractions), aspartate transaminase (AST), alanine transaminase (ALT), -glutamyl transpeptidase, and alkaline phosphatase levels.

- #87 Jaundice – Clinical Methods – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK413/
Jaundice is the yellow color of skin and mucous membranes due to accumulation of bile pigments in blood and their deposition in body tissues. Jaundice must be distinguished from yellow or green skin color resulting from carotenemia or quinacrine ingestion. The majority of jaundiced patients may be diagnosed by careful and meticulous history and physical examination. Assessment of constitutional symptoms often provides the first clue to the mechanism of jaundice. Symptoms associated with jaundice often provide a diagnosis. The jaundiced patient requires thorough documentation of all recent drug and toxin exposures. Potential contact with hepatitis viruses and other infectious agents should also be determined. Surgical history, whether recent or remote may be implicated in the cause of jaundice. Other systemic conditions may have complications related to the liver. A family history of jaundice, liver disease, or anemia should be sought. In most instances, physical examination of the jaundiced patient confirms a diagnosis suspected by history or provides diagnostic proof in its own right. Examination of the skin may reveal bruising resulting from disturbed blood coagulation mechanisms. Auscultation over the liver should be performed prior to manual manipulation of the area. Palpation of the liver is the single most crucial step in evaluation of the jaundiced patient. Splenomegaly is frequently found in the jaundiced patient, although its specific etiology is variable. Ascites in the jaundiced patient is an ominous sign, usually signifying severely decompensated cirrhosis with portal hypertension or malignancy. Dark urine resembling tea, which develops a green foam on shaking, is caused by bile pigment. Laboratory tests usually serve to confirm the pathophysiology of jaundice. The complete blood count may provide evidence for hemolysis by demonstrating anemia in a patient without blood loss. Liver function tests are nonspecific indicators of liver disease. Normal serum bilirubin concentration is usually no greater than 1.5 mg/dl and is composed primarily of the unconjugated form. Serum alkaline phosphatase is often elevated to at least three times the upper limit of normal in patients with jaundice due to intra- or extrahepatic obstruction. Transaminase elevations are common in both hepatocellular and obstructive jaundice. Prothrombin precursor is a protein manufactured by the liver whose full expression of activity in coagulation relies on a vitamin K-dependent carboxylase. Albumin is synthesized in the liver. Serologic assays for hepatitis A and B viruses should be performed in cases of acutely developing jaundice. Imaging investigation should start with a chest x-ray and plain film of the abdomen. Abdominal sonography is a valuable screening test in the jaundiced patient. Computerized tomography has the advantage of surveying the entire abdomen as well as the hepatobiliary-pancreatic axis. Until recently, hepatobiliary scintigraphy had little to contribute to the differential diagnosis of jaundice. Percutaneous transhepatic cholangiography involves passage of a thin needle into the liver under fluoroscopic guidance and injection of contrast into the biliary tree. Endoscopic retrograde cholangiopancreatography is performed by passing a flexible fiberoptic endoscope into the patient’s duodenum. The most important question to answer in the evaluation of any jaundiced patient is, „Will this patient require surgery to relieve biliary obstruction?”

Jaundice is not a common presenting complaint in adults. When present, it may indicate a serious problem. This article discusses the evaluation of the adult patient with jaundice. A systematic approach is warranted to clarify the cause quickly so that treatment can begin as soon as possible. […] The initial work-up of the patient with jaundice depends on whether the hyperbilirubinemia is conjugated (direct) or unconjugated (indirect). A urinalysis that is positive for bilirubin indicates the presence of conjugated bilirubinemia. Conjugated bilirubin is water soluble and therefore able to be excreted in urine. The findings of urinalysis should be confirmed by measurements of the serum total and direct bilirubin levels. […] First-line serum testing in a patient presenting with jaundice should include a complete blood count (CBC) and determination of bilirubin (total and direct fractions), aspartate transaminase (AST), alanine transaminase (ALT), -glutamyl transpeptidase, and alkaline phosphatase levels.

Jaundice, or icterus, is yellowish discoloration of the skin, mucous membranes, sclerae, and body fluids resulting from excess accumulation and deposition of bilirubin in the body in the presence of serum hyperbilirubinemia. […] To appreciate the differential diagnosis of jaundice requires an understanding of the fundamental metabolism of bilirubin; the risk factors, epidemiology, and pathophysiology of common causes of jaundice; and the available serologic and imaging studies used in the workup of jaundiced patients. […] The differential diagnosis for jaundice is based on whether the disease responsible for jaundice is prehepatic (primarily unconjugated hyperbilirubinemia), hepatic (mixed hyperbilirubinemia), or posthepatic (conjugated hyperbilirubinemia). […] The initial steps in evaluating the jaundiced patient are to determine whether the hyperbilirubinemia is predominantly conjugated or unconjugated; whether the disease process responsible for jaundice is likely to be hemolytic, hepatocellular, or cholestatic; and whether other biochemical liver test results are abnormal.
- #91 Testing for Jaundice | VCA Animal Hospitalshttps://vcahospitals.com/know-your-pet/testing-for-jaundice
The major feature noted on the serum biochemistry profile when increased red blood cell destruction is the cause of jaundice is an increase in the serum bilirubin concentrations (hyperbilirubinemia). […] A urinalysis confirms the presence of hyperbilirubinemia by documenting increased amounts of bilirubin in the urine. […] Occasionally, immune-mediated destruction of red blood cells is suspected but cannot be definitively confirmed with the above screening tests. […] The CBC may indicate the presence of inflammation or infection within the liver and/or gall bladder by an increased white blood cell count. […] Although changes in the biochemistry profile may support the diagnosis of liver disease, they rarely indicate the exact cause. […] Destruction of individual liver cells (hepatocytes) is indicated by increases in the liver enzymes ALT (alanine aminotransferase) and AST (aspartate transaminase).

Imaging studies can be helpful in identifying the etiology of conjugated (direct) hyper-bilirubinemia. An elevated direct bilirubin level suggests obstructive jaundice, and ultrasound or computed tomographic (CT) imaging may identify the responsible structural lesion.

Unconjugated or conjugated bilirubin levels in the blood are rising. All jaundiced patients should undergo extra tests in addition to the liver panel, such as the albumin and prothrombin time tests, which are indicators of chronic and acute liver function, respectively. Prothrombin time’s failure to decrease after receiving parenteral vitamin K indicates severe hepatocellular dysfunction. […] The outcomes of the bilirubin, enzyme, and liver function tests will point the doctor in the direction of a hepatocellular or cholestatic cause and provide some insight into the length and intensity of the illness.

Tests must be performed to determine whether your infant has excessive amounts of a substance called bilirubin in their blood, as treatment is typically only required if this is the case. […] The majority of infants with jaundice do not require treatment since their blood bilirubin levels are reported to be low. In these situations, the problem often improves within 10 to 14 days and won’t harm your child. […] Your infant may need to be taken to the hospital and treated with phototherapy or an exchange transfusion if their jaundice does not go better on its own or if testing reveal elevated levels of bilirubin in their blood. […] Prevention of jaundice depends on the disorder causing it. Some of the illnesses might not be preventable. To lessen your risk of getting jaundice, follow these recommendations: Consume alcohol in moderation. No more than two drinks per day for men and one drink per day for women are considered moderate. Be cautious while combining alcohol and other drugs, such acetaminophen. Avoid coming into contact with industrial chemicals. Never exchange needles or nasal snorting supplies. Practice safe sex. Get the hepatitis A vaccine to lower your risk of contracting the disease. Get the hepatitis B vaccine to lower your risk of contracting the disease.

The challenge for the clinician is to establish the cause of jaundice and, as part of this, decide whether jaundice represents a benign and self-limiting condition or a serious underlying illness. […] The patients clinical presentation is suggestive of acute hepatitis. […] Although jaundice in neonates is common and normal, especially in breast-fed babies, both early jaundice (within the first week of life) and prolonged jaundice (jaundice persisting beyond the first 14 days) may be indicators of an underlying medical condition. […] In a child with prolonged jaundice, the clinician must always consider biliary atresia as a possible cause, and early diagnosis of this condition is crucial. […] Jaundice with predominantly raised ALP and only moderately raised ALT suggests a cholestatic or post-hepatic picture, in which the biliary tree external to the liver is blocked.

Diagnosing Jaundice […] Your doctor will ask you about your symptoms and medical history. They’ll then give you a physical exam to see if there’s swelling in your liver. […] To get more information, your doctor will likely order blood tests to measure bilirubin and cholesterol levels and get a complete blood count (CBC). If you have jaundice, your level of bilirubin will be high. Your doctor may order other tests to find the cause of your jaundice and how severe it is, including: […] A hepatitis panel, which is a blood test that shows if you have, or have had, hepatitis. It tests for hepatitis A, hepatitis B, and hepatitis C. If there are no hepatitis antibodies in your blood, it means you don’t have the condition, or you had it in the past, but your body has cleared it. […] Tests to check enzyme levels in the liver to see how well it is functioning. If enzyme levels are higher or lower than normal, it can mean you have disease or damage to the liver or bile ducts. […] Imaging, like a CT scan, ultrasound, or magnetic resonance cholangiopancreatography, a type of MRI that checks for blocked ducts near the gallbladder […] A liver biopsy, to show if you have damage to, or disease in, your liver. During the test, a small piece of your liver is removed either with a needle inserted into the belly to the liver, through a vein in your neck, or through a cut in your belly. […] Prothrombin time, which measures how long it takes for blood plasma to clot. Your blood will be taken, and a laboratory will test it to see if it clots faster or slower than the normal range (which is between 10 and 13 seconds). If it clots too slowly, that may mean there are problems with your liver.

Jaundice, derived from the French word for yellow, jaune, can be a patients presenting symptom or a clinical sign identified by a clinician. It describes a yellow or sometimes greenish-yellow pigmentation of the skin, conjunctiva, and mucous membranes that is caused by raised plasma bilirubin. Jaundice usually becomes clinically apparent when a patients serum bilirubin concentration reaches 4050micromol/l. […] Jaundice can present at any age. It can be caused by a wide range of disorders that includes benign conditions, those that can result in permanent and irreversible liver damage, and those that are rapidly life threatening. Jaundice is the result of dysfunction in the bilirubin metabolism pathway, and its causes can be categorised as pre-hepatic (for example, excessive breakdown of red blood cells), intra-hepatic (for example, disease-related perturbation of liver function or intrahepatic anatomy), or post-hepatic (for example, obstruction of the bile ducts).

The traditional phenotypic diagnosis includes low GGT as a signature of PFIC1 (FIC1 defect) and PFIC2 (BSEP defect). […] For patients suspecting jaundice or cholestasis, routine liver biochemistry tests include total and direct bilirubin levels, aspartate transferase levels, ALT levels, GGT and alkaline phosphatase (ALP) levels. […] Genetic diagnosis is a definitive diagnosis for inherited genetic liver diseases, as many of these diseases lack adequate biomarkers. […] Liver transplantation is considered a curative treatment for various liver diseases.
