Questions
Why is antibody screening necessary? If the screening result is negative, does it mean everything is normal?
Answers
Antibody screening is a prenatal test used to detect irregular antibodies early, so that neonatal hemolytic disease can be prevented and treated during pregnancy. Generally, a negative screening result is normal. However, if the result is positive, even when transfusing identical blood types, a transfusion reaction may occur. To ensure timely blood transfusion in case of massive bleeding during delivery, it is very necessary to conduct prenatal screening and not wait until after bleeding occurs. Therefore, most people with negative results have nothing to worry about.
