Patient's question:
Mother is O type, father is AB type. By conducting a blood test for anti-A, anti-B, and anti-coagulation factor, can we infer whether the child's blood type is the same as the mother's? If the mother is O and the father is AB, the child will either be A or B. Therefore, if the blood test results for anti-A, anti-B, and anti-coagulation factors can be obtained, can we infer whether the child's blood type is the same as the mother's? If the child is O type, the results will definitely be different from those obtained from a fetus with A or B type blood, right?Doctor's answer:
Analysis of the condition: Your issue is simply about the ABO blood type problem. Are you concerned about neonatal hemolysis? ABO blood type is classified based on antigens on the surface of red blood cells. Simply put, if the surface of red blood cells has A antigens, it is A-type blood; if it has B antigens, it is B-type blood; if it has both A and B antigens, it is AB-type blood; and if it has neither, it is O-type blood. Neonatal hemolysis is most likely to occur in a mother with O blood type and a child with B blood type.Advice: If the mother has O blood type and the father has AB blood type, the child could be either A or B type, but not any other blood type. It is risky but not guaranteed to occur. It is important to take it seriously but not over worry. Pay attention during the perinatal period, undergo prenatal check-ups on schedule, and take appropriate preventive measures.
