Question

A pregnant woman underwent IgG anti-A and anti-B titer tests at 16 weeks, and found that the anti-A titer was 256 and the anti-B titer was 128, both higher than the reference value of 64. She inquires about the situation and whether it has any impact.

Answer

The physician advises that this condition may be ABO blood incompatibility, which often occurs in pregnant women with O-type blood. Although the antibody titer is currently high, it does not necessarily mean that hemolysis will occur. It is recommended to take Chinese medicine such as rhubarb, tangerine, and artemisia for prevention, or to adopt Western medicine such as high osmotic sugar, vitamin C combined with vitamin E, and other preventive measures.
