For pregnant women with blood type O, when is the latest week to test for hemolytic disease?
Disease description:
I heard that hemolytic disease screening is required during prenatal checkups, but I forgot to have it done earlier. For an O-type blood pregnant woman, what is the latest gestational week by which this test should be performed?

In general, it is recommended to undergo a blood test around 20 weeks of gestation to determine whether hemolysis is present. Regular prenatal check-ups must be attended on schedule throughout pregnancy to closely monitor fetal development. After becoming pregnant, it is essential to maintain a balanced diet—consuming more fresh fruits and vegetables can help boost immunity. Additionally, avoid excessive stress and strive to maintain a positive, relaxed mood.
