Which department should couples visit for hemolysis testing?

   Couples should visit the obstetrics department for testing related to hemolytic disease. Specific details are as follows:

   If the woman has blood type O and her husband has blood type A, B, or AB, this may lead to incompatibility between the newborn's and mother's blood types, resulting in ABO hemolytic disease. If the newborn also has blood type O, hemolytic disease typically does not occur. Therefore, ABO hemolysis testing is generally unnecessary before pregnancy and can be performed during pregnancy instead. If increased ABO hemolytic antibodies are detected during pregnancy, regular prenatal checkups at the hospital are required.

   Both partners should be present when undergoing hemolysis testing. If the mother is Rh-negative and the father is Rh-positive, this may also cause blood type incompatibility between mother and child, although the probability of this occurring is relatively low. Since neonatal hemolytic disease can lead to serious adverse outcomes, couples should undergo relevant tests before having children.

   In addition, if signs of ABO hemolysis are detected, immunoglobulin injections under medical guidance can effectively reduce the risk of ABO hemolysis. If a newborn is diagnosed with ABO hemolysis after birth, phototherapy treatment may be administered under a doctor’s supervision.
