[Release: Webmaster] [2015-5-22] [Close]

Amniotic fluid puncture is a method of prenatal diagnosis, which is generally suitable for prenatal diagnosis of mid-term pregnancy. 周,因为那时的羊水量最多,太早羊水不够抽取标本困难,容易伤及胎儿,太晚,胎儿已发育成形,此时发现异常,不适于继续妊娠需终止妊娠,施行手术时,会使操作困难,也增加母体的危险性。 The best time for amniocentesis is 16-21 weeks of gestation. Because the amount of amniotic fluid is the largest at that time, it is not enough to extract the specimens too early, it is easy to hurt the fetus, it is too late, and the fetus has developed and formed. Pregnancy needs to be terminated. When surgery is performed, it will make the operation difficult and increase the risk of the mother.

They have also been exposed to harmful substances and have rubella virus At the time of infection, the fetus may be adversely affected, so an amniotic fluid puncture test must also be performed.
