  https://my.clevelandclinic.org/health/diseases/12361-sepsis

  Sepsis is a life-threatening medical emergency caused by your body’s overwhelming response to an infection. Without urgent treatment, it can lead to tissue damage, organ failure and death. […] It’s very important to quickly identify people with infections that may go on to develop sepsis. There are no strict criteria to diagnose sepsis. That’s why providers use a combination of findings from a physical exam, lab tests, X-rays and other tests to identify the infection (blood cultures) and diagnose sepsis. […] If your provider diagnoses you with sepsis, they’ll usually place you in the intensive care unit (ICU) of the hospital for special treatment. You may receive the following treatment for sepsis: Antibiotics: You’ll receive antibiotics if you have a bacterial infection. […] Sepsis is a life-threatening medical emergency. To avoid sepsis, make sure to get treatment for any infections immediately. If you delay treatment, a simple infection could lead to a deadly condition.

  https://healthcare-in-europe.com/en/news/exploring-the-importance-challenges-of-early-sepsis-diagnosis.html

  „Sepsis is one of the most deadly and costly medical conditions physicians and hospitals must face. In fact, statistics show that sepsis is the third leading cause of death in the U.S. Mortality rates for sepsis is extremely high approximately 25-30% with more individuals dying of sepsis than prostate cancer, breast cancer, and HIV combined. Early detection of sepsis is critical, as a delay in antibiotic treatment has been documented to result in increased mortality, with a 7.6% increase in death for patients with severe sepsis and septic shock every hour antibiotic administration is delayed. Therefore, the earlier sepsis is recognized and the earlier the treatment starts, the better the outcome for the patient and the lower the cost that can be expected to be borne by the healthcare system.”

• #17 Laboratory Evaluation of Sepsis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK594258/

  Sepsis is evaluated with various laboratory studies, including different biomarkers essential for diagnosis, early recognition of severity, risk stratification, and prognosis. These studies also have a role in dictating management and antibiotic stewardship. The initial management of a patient with suspected sepsis includes evaluation for the source of infection, severity assessment, treatment and prevention of hypotension, intravenous fluids, vasopressors, antibiotics, and infection source control. The severity of sepsis is determined through physical examination and laboratory evaluation. […] The laboratory workup for patients with suspected sepsis includes blood lactate, complete blood count with differential (CBC), chemistry panel, and liver function tests (LFTs). Using this laboratory data, along with clinical findings, is essential in stratifying the severity of the disease. The SOFA score is used to define sepsis and has prognostic and therapeutic value. This scoring system allows clinicians to assess organ dysfunction, the characterizing feature of sepsis and septic shock, and evaluates the respiratory, cardiovascular, hepatic, renal, hematologic, and central nervous systems.

• #18 Laboratory Evaluation of Sepsis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK594258/

  In addition to cultures and testing to identify causative pathogens, diagnostic tests used in evaluating sepsis include those that have proven utility in identifying systemic inflammatory response syndrome (SIRS) and organ dysfunction. These tests usually include the CBC, clinical chemistry, and arterial blood gas. Host-response and pathogen-specific biomarkers have been described in the literature as having utility in staging disease severity, prognosis, and response to treatment. Some common host-response biomarkers used in regular practice include C-reactive protein (CRP), lactate, and procalcitonin (PCT). […] The SOFA score assesses organ dysfunction, and most of the data required to calculate an accurate SOFA score is readily available through clinical assessment and commonly performed laboratory testing. An important limitation of the SOFA criteria is the scoring of respiratory dysfunction, which requires a PaO2 value to obtain the PaO2/FiO2 ratio.

  „Diagnosing sepsis early is very challenging, because symptoms may not be obvious and clear at the time at which the patient presents at the hospital.” […] „Practically speaking, clinicians may use SIRS criteria (if they are still using sepsis-2) or the SOFA score (sequential organ failure assessment, if they use the sepsis-3 definition) to diagnose sepsis. Additionally, laboratory tests are used to test for infection and help confirm a suspicion of sepsis; for example, by measuring the patient’s WBC (white blood cell) count, Procalcitonin, C-Reactive Protein, Interleukin-6 or presepsin levels, or culturing body fluids such as blood or urine for infectious organisms. While positive cultures may be diagnostic of infection, none of these tests can definitively confirm a diagnosis of sepsis, so clinicians must rely on all the clinical and laboratory information available together to diagnose sepsis.”

  Unlike diseases or conditions like diabetes or kidney stones, there is no one test for sepsis. However, your doctor makes the diagnosis by evaluating your symptoms, your history, and other tests. This can then lead your doctor to suspect you have sepsis. […] None of these tests can diagnose sepsis, but when the test results are combined with information about your illness and a physical examination, they can help your doctor determine if you have sepsis: […] The following tests are what doctors call confirmatory or diagnostic tests. The test results give the medical team more information when they suspect sepsis. […] If your doctor suspects sepsis, treatment (with fluids and antibiotics) should begin right away, while waiting for these confirmatory test results. […] Endotoxin is a component of certain bacteria, released when the bacteria cell disintegrates. It should not be in your blood, so its presence confirms there are gram negative bacteria in your bloodstream, although this test cannot identify which type.

  These criteria are more specific for sepsis but come at the expense of sensitivity, leading to concerns that many sepsis diagnoses could be delayed or missed. […] The major challenge, which none of the sepsis definitions address, is the difficulty in determining whether or not patients are infected, particularly in the early stages of presentation. […] Although procalcitonin testing can aid in the diagnosis of bacterial infection and sepsis, the test has imperfect sensitivity and specificity. […] Central to the pathophysiology of sepsis is the presence of organ dysfunction, such as hypotension, elevated lactate, respiratory failure, altered mental status, renal failure, or coagulopathy, but these are also not specific to sepsis. […] The challenges in identifying sepsis have spurred the development of various clinical decision support tools, most notably alerts that flag patients based upon real-time information in a patient’s electronic health record (EHR).

  Multiple clinical, laboratory, radiologic, and microbiologic data are required for the diagnosis of sepsis and septic shock. Sepsis should never be diagnosed based on a single abnormality. However, the diagnosis is often made empirically at the bedside upon presentation or retrospectively when follow-up data return (eg, positive blood culture result) or a response to antibiotics is evident. Importantly, the identification of a pathogenic organism, although preferred, is not always feasible since the responsible organism may be unidentified in many patients. […] In general, the workup for sepsis may include the following: Blood culture and urine analysis and culture; Chemistry studies that can suggest organ dysfunction, such as liver or kidney function tests; Serum lactate levels obtained urgently and serially; Chest radiology; Diagnostic imaging of the chest and abdomen/pelvis; Cardiac studies such as ECG and troponins, as indicated; Interventions such as paracentesis, thoracentesis, lumbar puncture, or aspiration of an abscess, as clinically indicated; Measurement of biomarkers of sepsis such as procalcitonin levels.

  Diagnosing sepsis remains problematic. Pathogen identification is frequently lacking and the dysregulated host response is non-specific. Blood cultures often take days to deliver a result and, even then, approximately 90% are negative, sometimes despite strong clinical evidence of sepsis. Standard host-response biomarkers such as C-reactive protein (CRP), procalcitonin (PCT) and white cell count are routinely utilised; however, these are insufficiently discriminatory and lack specificity. This is especially challenging in the intensive care unit (ICU) setting where many patients have underlying sterile inflammation that can closely mimic clinical and laboratory features of sepsis. Despite the arrival of multiple new sepsis biomarkers over the years, none has yet achieved widespread adoption by consistently outperforming the standards.
