Patient's question:
Antibody titer results: Pregnant woman O-type Rh(+) Husband A-type Rh(+) ABO blood type IgG antibody anti-A (anti-B) titer: 1:4The above is the test result. The doctor said it is not ideal and suggested checking again next month. How is this result? The Down syndrome screening was low risk, and all trace elements were normal.
Doctor's answer:
Analysis of the condition: ABO incompatibility between mother and child occurs when the mother is type O and the child is type A or B. ABO blood group incompatibility is the main cause of neonatal hemolytic disease in China and a common cause of hyperbilirubinemia. This condition accounts for 0.3% of stillbirths, 27.2% of severe hyperbilirubinemia, 1.4% of neonatal deaths, and 5.9% of cases of bilirubin encephalopathy.Advice: When the titer of anti-A and anti-B antibodies is higher than 1:128, the incidence of neonatal hemolytic disease is relatively high. In your case, the titer of ABO IgG antibodies anti-A (anti-B) is 1:4, which falls within the normal range. There is no need for treatment or concern! However, dynamic observation is necessary.
