Why do antibody screening

Patient's question:

The result of the irregular antibody screening for pregnant women is negative, should there be no problem?

Doctor's answer:

1 Hello, pregnant women undergoing irregular antibody screening can detect irregular antibodies early, which allows for the prevention and treatment of neonatal hemolytic disease during pregnancy.
2 Irregular antibody screening is a pre-transfusion test. If antibodies are positive, even blood of the same blood type may cause a transfusion reaction. To avoid the risk of delayed blood transfusion during childbirth in case of severe bleeding—since it is not feasible to wait until bleeding occurs to conduct these tests—all pregnant women are required to undergo screening before delivery.
3 Most people test negative, and a negative result indicates normalcy, so please do not worry.
