  https://www.chop.edu/conditions-diseases/rh-disease

  Rh disease occurs during pregnancy when there is an incompatibility between the blood types of the mother and baby. […] Early identification of the Rh negative mother is very important. Then, the risks for the baby can be determined by blood testing of both parents (Rh negative mother, Rh positive father). The disease may be diagnosed if a previous pregnancy resulted in an Rh positive baby. In addition to a complete medical history and physical examination, diagnostic procedures for Rh disease may include: […] Testing the presence of Rh positive antibodies in the mother’s blood […] Ultrasound to detect organ enlargement or fluid build up in the fetus. Ultrasound is a diagnostic imaging technique that uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs.

  Rhesus disease is usually diagnosed during the routine antenatal checks and tests you’re offered during pregnancy. […] If you’re RhD negative, your blood will be checked for the antibodies (known as anti-D antibodies) that destroy RhD positive red blood cells. […] If anti-D antibodies are detected in your blood during pregnancy, there’s a risk that your unborn baby will be affected by rhesus disease. […] It’s possible to determine if an unborn baby is RhD positive or RhD negative by taking a simple blood test during pregnancy. […] If your baby is RhD negative, they’re not at risk of rhesus disease and no extra monitoring or treatment will be necessary. […] If a Doppler ultrasound shows your baby’s blood is flowing faster than normal, a procedure called foetal blood sampling (FBS) can be used to check whether your baby is anaemic (iron deficiency anaemia). […] If you’re RhD negative, blood will be taken from your baby’s umbilical cord when they’re born. This is to check their blood group and see if the anti-D antibodies have been passed into their blood. This is called a Coombs test.

  Rh positive is much more common than Rh negative. […] Your health care provider will advise that you have a blood type and Rh factor screening test during your first prenatal visit. This will show whether you are Rh positive or Rh negative. […] If you’re Rh negative, you might need to have another blood test called an antibody screen several times: during your first trimester, during week 28 of pregnancy and when your baby is born. Some people need the test more often. […] That test is used to detect antibodies to Rh positive blood. If you haven’t started to produce Rh antibodies, you’ll likely need a shot (injection) of a blood product called Rh immune globulin. This prevents your body from producing Rh antibodies during your pregnancy. […] If your baby is born Rh positive, you’ll need another injection shortly after delivery.

  https://www.merckmanuals.com/professional/gynecology-and-obstetrics/antenatal-complications/hemolytic-disease-of-the-fetus-and-neonate

  Hemolytic disease of the fetus and neonate is hemolytic anemia in the fetus or neonate caused by transplacental transmission of maternal antibodies to fetal red blood cells. Diagnosis begins with prenatal maternal antigenic and antibody screening and may require paternal screening, serial measurement of maternal antibody titers, and fetal testing. […] At the first prenatal visit, all women are screened for blood type, Rh type, and anti-Rho(D) and other antibodies that are formed in response to antigens and that can cause hemolytic disease of the fetus and neonate (reflex antibody screening). […] If women have Rh-negative blood and test positive for anti-Rho(D) or they test positive for another antibody that can cause hemolytic disease of the fetus and neonate, the fathers blood type and zygosity (if paternity is certain) are determined.

• #1 Coombs Test: Purpose, Procedure & Results

  https://my.clevelandclinic.org/health/diagnostics/22978-coombs-test

  A Coombs test checks for antibodies that can attack your red blood cells. Antibodies are a vital part of your immune system. They fight off antigens (like bacteria, viruses and other toxins) to keep you healthy. But sometimes antibodies mistakenly attack normal, healthy cells instead. […] First, its important to note that there are two different types of Coombs tests: direct and indirect. […] Direct Coombs test (sometimes called a direct antiglobulin test) looks at your red blood cells to see if there are antibodies attached to them. Its often used to diagnose blood-related conditions such as autoimmune hemolytic anemia. […] Indirect Coombs test tells your provider if there are antibodies present in your bloodstream that could attach to red blood cells. Its used as a screening process to see how youll react to a blood transfusion. An indirect Coombs test is also routinely given as part of prenatal testing.

• #1 Coombs Test: Purpose, Procedure & Results

  https://my.clevelandclinic.org/health/diagnostics/22978-coombs-test

  A positive (abnormal) Coombs test means that you have antibodies that can attack your red blood cells. […] If you test positive during your pregnancy, it means youll need to take steps to protect the fetus from Rh sensitization. […] Generally, a positive Coombs test result indicates anemia or jaundice. […] A negative (normal) test result is good news. It means that no antibodies attached to red blood cells were found. […] If you develop symptoms of hemolytic anemia, such as jaundice, weakness, dizziness or confusion, call your healthcare provider right away. […] The Coombs test looks for antibodies that may attack and destroy your red blood cells.

• #1 Coombs Test: Purpose, Procedure & Results

  https://my.clevelandclinic.org/health/diagnostics/22978-coombs-test

  Your provider will give you an indirect Coombs test if you’re pregnant to see if you have antibodies against Rh-positive blood. […] If an Rh-negative person is pregnant with an Rh-positive fetus, then Rh sensitization can occur. […] Therefore, during your first pregnancy, the fetus probably wouldnt be affected. However, if you get pregnant again with an Rh-positive fetus, the existing antibodies in your blood could attack its red blood cells. This can result in Rh disease, which is characterized by anemia, jaundice or other serious health problems. […] If youre at risk for Rh sensitization, treatment can almost always prevent this problem. If youre already sensitized, then treatment can help protect the fetus. […] If your baby is born with jaundice, then your healthcare provider will likely perform a Coombs test. This helps detect any foreign antibodies that have attached to your newborns red blood cells.

• #1 Rh Incompatibility: Symptoms, Diagnosis & Treatments

  https://www.healthline.com/health/rh-incompatibility

  A blood test to determine your Rh status will likely be done at your first prenatal visit with your doctor. […] A positive indirect Coombs test is a sign of Rh incompatibility. This test uses a blood sample to look for the presence of cell-destroying antibodies within the plasma of your blood. […] Higher-than-normal levels of bilirubin in your infant’s blood is a sign of Rh incompatibility. In a full-term baby who is less than 24 hours old, the levels of bilirubin should be less than 6.0 milligrams per deciliter. […] Signs of red blood cell destruction in your infant’s blood may indicate Rh incompatibility. This can be determined by the shape and structure of the red blood cells when examined under a microscope. […] Your doctor can test your baby’s blood for the presence of maternal antibodies that are breaking down the red blood cells.

• #1 Rh incompatibility: MedlinePlus Medical EncyclopediaLock

  https://medlineplus.gov/ency/article/001600.htm

  Rh incompatibility is a condition that develops when a pregnant woman has Rh-negative blood and the baby in her womb has Rh-positive blood. […] Rh incompatibility can cause symptoms ranging from very mild to deadly. In its mildest form, Rh incompatibility causes the destruction of red blood cells. There are no other effects. […] Before delivery, the mother may have more amniotic fluid around her unborn baby (polyhydramnios). […] A positive direct Coombs test result […] Higher-than-normal levels of bilirubin in the baby’s umbilical cord blood […] Signs of red blood cell destruction in the infant’s blood […] Rh incompatibility can be prevented with the use of RhoGAM. Therefore, prevention remains the best treatment. […] Special immune globulins, called RhoGAM, are now used to prevent RH incompatibility in mothers who are Rh-negative. […] These injections prevent the development of antibodies against Rh-positive blood.

  If maternal anti-Rh antibody titers are positive but less than a laboratory-specific critical value (usually 1:8 to 1:32), they are measured every 2 to 4 weeks after 20 weeks. […] When Rho(D) status is uncertain, noninvasive cell-free fetal DNA screening of maternal blood for the RHD gene can be done. […] If fetal anemia is likely, the fetus can be given intravascular intrauterine blood transfusions by a specialist at an institution equipped to care for high-risk pregnancies. […] Maternal sensitization and antibody production, which are the cause of hemolytic disease of the fetus and newborn, can be prevented by giving the woman Rho(D) immune globulin. […] Rho(D) immune globulin is given routinely to all Rh-negative pregnant women with no known prior sensitization and a fetus that might be Rh-positive. […] If the presence of fetomaternal hemorrhage is uncertain, a rosette test (addition of an anti-D reagent to maternal blood) is used as an initial qualitative screening test.

• #1 Rh Incompatibility Workup: Laboratory Studies, Imaging Studies

  https://emedicine.medscape.com/article/797150-workup

  Determination of Rh blood type is required in every pregnant female. […] In a pregnant woman with Rh-negative blood type, the Rosette screening test often is the first test performed. The Rosette test can detect alloimmunization caused by very small amounts of fetomaternal hemorrhage. […] Point-of-care blood tests have become available for use in the emergency department and have been shown to have very high sensitivity and specificity in determining Rh status. […] Obtaining maternal Rh antibody titers can be helpful for future follow-up care of pregnant females who are known to be Rh negative and may be initiated from the ED. High levels of maternal Rh antibodies suggest that Rh sensitization has occurred, and further studies, such as amniocentesis and/or cordocentesis, may be necessary to evaluate the health of the fetus.

  If Rh-D negative women are isoimmunized, it is necessary to determine the anti-D antibody titer, as this titer correlates with the severity of the disease and determines the need for fetal anemia studies with Doppler velocimetry of the MCA. […] Doppler ultrasound of the MCA is suggested for Rh-D negative patients with a positive indirect Coombs test and titers 1:16. […] The consensus suggests Cordocentesis when fetal anemia is suspected, and intrauterine fetal transfusion when cordocentesis shows severe fetal anemia. […] It is essential to address Rh-D negative pregnant women, isoimmunized women, and fetuses with Rh disease in an appropriate and standardized manner, according to the Colombian context, across all levels of prenatal care. The recommendations issued in this consensus are expected to improve clinical care, as well as enhance perinatal health and neonatal quality of life in cases of Rh disease.

  https://www.sciencedaily.com/releases/2018/05/180515105651.htm

  Prenatal testing of the fetal rhesus factor: Test is reliable, but benefit is unclear. The new noninvasive test, using a blood sample of the pregnant woman, is as reliable as the conventional test using a blood sample of the newborn. The reliability of the new test is as high as the reliability of the conventional test used after birth, however. The reliability is comparatively high, which is referred to as „high diagnostic accuracy”: The test correctly identifies 99.9 per cent of all Rh-positive fetuses (sensitivity) and 99.1 per cent of all Rh-negative fetuses (specificity). Hence, the prenatal test is as reliable as testing after birth. The new test allows using the anti-D prophylaxis when it is needed and spare some pregnant women from unnecessary prenatal prophylaxis. If the prenatal test was to replace the postnatal test, this would increase neither the rate of prophylaxis that is falsely withheld nor the rate of haemolytic anemia to a measurable extent. Both tests are equivalent. […] The IQWiG researchers found out that there are currently no studies that allow drawing precise conclusions on the effects the introduction of the new test might have.

  In the United States, it is a standard of care to test all expecting mothers for the presence or absence of the RhD protein on their RBCs. However, when medical care is unavailable or prenatal care not given for any other reason, the window to prevent the disease may be missed. […] At the first prenatal visit, the mother is typed for ABO blood type and the presence or absence of RhD using a method sensitive enough to detect weaker versions of this antigen (known as weak-D) and a screen for antibodies is performed. […] If she is negative for RhD protein expression and has not formed anti-D already, she is a candidate for RhoGam prophylaxis to prevent alloimmunization. […] If the screening test is positive or the appropriate dose of RhoGam needs to be determined, a quantitative test is performed to determine a more precise amount of fetal blood to which the mother has been exposed. […] There are also emerging tests using Cell-free DNA. Blood is taken from the mother, and using PCR, can detect fetal DNA.

[…] If you’re Rh negative, you might need to have another blood test called an antibody screen several times: during your first trimester, during week 28 of pregnancy and when your baby is born. Some people need the test more often. […] That test is used to detect antibodies to Rh positive blood. If you haven’t started to produce Rh antibodies, you’ll likely need a shot (injection) of a blood product called Rh immune globulin. This prevents your body from producing Rh antibodies during your pregnancy. […] If your baby is born Rh positive, you’ll need another injection shortly after delivery.

  An Rh-D negative patient is considered isoimmunized if: a) the indirect Coombs test is positive at any titer, provided anti-D IgG was not received in the previous month, or b) there is a history of adverse perinatal outcomes associated with Rh disease in prior pregnancies, such as hydrops. […] If Rh-D negative women are isoimmunized, it is necessary to determine the anti-D antibody titer, as this titer correlates with the severity of the disease and determines the need for fetal anemia studies with Doppler velocimetry of the MCA. […] Doppler ultrasound of the MCA is suggested for Rh-D negative patients with a positive indirect Coombs test and titers 1:16. […] The consensus suggests Cordocentesis when fetal anemia is suspected, and intrauterine fetal transfusion when cordocentesis shows severe fetal anemia. […] It is essential to address Rh-D negative pregnant women, isoimmunized women, and fetuses with Rh disease in an appropriate and standardized manner, according to the Colombian context, across all levels of prenatal care.
