Patient's question:
Can you still have an amniocentesis? Do you need to make an appointment to do it at Shengjing Hospital? How do you make an appointment? I'm from a place outside the city.Doctor's answer:
Analysis of the condition: Hello! The optimal time for amniocentesis during prenatal diagnosis is between weeks 16 and 24 of pregnancy. It can be used for fetal chromosome karyotyping, diagnosis of chromosomal genetic diseases, and determination of fetal sex. It can also be used for genetic disease diagnosis and metabolic disease diagnosis using amniotic fluid cell DNA. Measuring alpha-fetoprotein in amniotic fluid can also diagnose fetal open neural tube defects and other conditions. If the pregnancy is in the late stage, amniocentesis can determine blood type, bilirubin, lecithin, sphingomyelin, placental lactogen, etc., to assess whether there is maternal-fetal blood type incompatibility, hemolysis, fetal lung maturity, skin maturity, placental function, and other conditions.Advice: Amniocentesis can be performed at 7 months of pregnancy, but the content of the examination will be different. I don’t know which aspect of the examination you need for the amniotic fluid sampling.
