Amniocentesis is a medical procedure that involves the withdrawal of a small amount of amniotic fluid using a needle inserted through the abdominal wall into the uterus. This fluid contains cells shed by the fetus, which can then be analyzed for various purposes. The procedure is typically performed between the 15th and 20th week of pregnancy, though it can be done later if necessary.

The primary use of amniocentesis is for prenatal diagnosis of chromosomal abnormalities and genetic defects. By analyzing the fetal cells, doctors can detect conditions such as Down syndrome, cystic fibrosis, and spina bifida. It can also be used to assess fetal lung maturity in later pregnancy, particularly when premature delivery is being considered. Additionally, amniocentesis can help diagnose fetal infections and determine the Rh factor compatibility between mother and fetus.

The procedure itself is relatively safe, but like any invasive medical intervention, it carries some risks. These include a small risk of miscarriage, infection, leakage of amniotic fluid, and injury to the fetus. Before undergoing amniocentesis, healthcare providers discuss the benefits and risks with the patient to ensure informed consent. The collected amniotic fluid is sent to a laboratory for specialized testing, and results are typically available within a few weeks.
