Analysis of the ABO Blood Group Antibody Effect Price in 485 Case Pregnant Women of the "O" Group Blood

Objective:To study the relationship between the antibody titer of seriumanti-A(B) IgG and hemolytic disease of the newborn(HDN) in the O type blood pregnant women.Methods: Serum analysis method of blood group was used to detect the expression of anti-A(B) of IgG in 485 pregnant women,and to confirm the relationship between the antibody titer and hemolytic disease of the newborn(HDN).Results:We had detected the antibody titer in 483 women who have pregnanted for seven months and 2 women who have pregnanted for five months,the positive rate of antibody was 6.39%,31 cases among these people were detected above 3 times by dynamic monitoring.The antibody titer of serum anti-A(B) ≥1∶64 was 3.09%(15/485).There is a positive relationship between the antibody titer and hemolytic disease of the newborn(HDV).Conclusion: In order to prevent and treat the ABO HDN,It is suggested that blood type and antibody should be tested on those with blood type incompatibility before delivery.
