Patient's question:
Beijing University Third Hospital amniocentesis cost and obstetric specialist number how muchDoctor's answer:
Hello: The cost of amniocentesis is approximately between 1500-2000. Amniocentesis is a method of prenatal diagnosis. It is generally suitable for prenatal diagnosis in the second trimester of pregnancy. Amniotic fluid exists in the amniotic cavity; the fertilized egg forms the amniotic cavity on the seventh day of fertilization and begins to produce amniotic fluid. At 12 weeks of pregnancy, the amount of amniotic fluid is 50 milliliters, at 20 weeks it is 400 milliliters, at 36-38 weeks it is 1000-1500 milliliters, and it slightly decreases near the due date. The best time for amniocentesis to extract amniotic fluid for prenatal diagnosis is between 16-20 weeks of pregnancy. This is because the fetus is small at this time, and there is relatively more amniotic fluid. The fetus floats in the amniotic fluid, surrounded by a wide band of amniotic fluid. When extracting amniotic fluid with a needle, it is less likely to injure the fetus. Extracting 20 milliliters of amniotic fluid only accounts for 1/20 to 1/12 of the total amount, which will not cause the uterine cavity to suddenly shrink and lead to miscarriage. Moreover, at this time, the proportion of active cells in the amniotic fluid is the highest, and the cell culture survival rate is high, which can be used for,,,. Amniotic fluid cells can also be used for DNA to make genetic disease diagnosis and metabolic disease diagnosis. Measuring alpha-fetoprotein in the amniotic fluid can also diagnose fetal open neural tube defects, etc. In the late stages of pregnancy, amniocentesis can measure blood type, bilirubin, lecithin, sphingomyelin, placental lactogen, etc., to understand whether there is maternal-fetal blood type incompatibility, hemolysis, fetal lung maturity, skin maturity, placental function, etc.
