Amniocentesis

Amniocentesis is a diagnostic procedure that involves withdrawing a small amount of fluid from the sac surrounding the fetus. A long, thin needle is inserted through the abdomen and into the uterus, and a small amount of fluid is taken from the sac. Before the procedure, the exact location of the fetus is determined by ultrasound.

Amniocentesis can be used to diagnose a large number of genetic and chromosomal abnormalities in the fetus. It is also helpful for diagnosing the severity of Rh incompatibility, lung maturity, and neural tube defects (such as spina bifida).
