Patient's question:
I would like to ask when is the amniocentesis usually performed?Doctor's answer:
Analysis of the condition: Amniocentesis can be used for fetal chromosome karyotype analysis, chromosome genetic disease diagnosis, and gender determination. It can also be used to diagnose genetic diseases and metabolic diseases using amniotic fluid cell DNA. Measuring alpha-fetoprotein in the amniotic fluid can also diagnose fetal open neural tube defects.Recommendations: Amniocentesis is most suitable between weeks 16-18 of pregnancy. At this time, the amount of amniotic fluid is relatively high, the fetus is small, and it is a relatively stable period, making it less likely to injure the fetus or cause miscarriage.
