Patient's question:
My wife is about five and a half months pregnant. Since she has hepatitis B, the doctor wants to check the fetus's chromosomes and has recommended that she undergo an amniocentesis. I'm very worried and would like to consult about the risks of this procedure.Doctor's answer:
Guidance: Amniocentesis is used to detect fetal chromosomes. Modern puncture techniques are performed under ultrasound guidance, with precise positioning and relatively low risk.
