What should be done about the decline in prenatal screening for neonatal hemolytic disease?

Patient's question:

Female ABO blood type O, RH (D) positive
Male ABO blood type AB antibody titer 1,128 (reference value ≤ 1,64)
What kind of help do you need?
Doctor, hello. During my examination, the doctor said my antibody titer was high. The local hospital prescribed me a traditional Chinese medicine called Yinchen Decoction:
- Yinchen 9g
- Huangqin 9g
- Dahuang 4.5g
- Gancao 6g
To be taken once daily, decocted in water, with a 20-day course of treatment.
Should I take this? Will it affect the baby? Can it be cured? What if I don’t take it—will it affect the baby? If I take it, can it be cured?
I would like to ask: what should I do if the antibody titer continues to decline? What symptoms of hemolysis might the child exhibit after birth? Is there any risk to the baby’s life?

Doctor's answer:

The antibody titer of 1,128 is lower than normal, but it is not significantly high. The likelihood of recurrent hemolysis is relatively small. The medication prescribed by the doctor has no effect on the fetus and is used to reduce the antibody titer.
Recurrent hemolysis in newborns is relatively rare, but to take preventive measures as much as possible, you can take the medication prescribed by the doctor.
Newborn hemolytic disease has a significant impact on the child. Once the mother notices the symptoms of the child, she should take them to a regular hospital for diagnosis immediately. At the same time, pay close attention to the child's care. It is recommended to follow a proper diet and avoid spicy foods that may affect the condition. We hope the child can receive effective treatment and recover quickly!
