Amniocentesis is a medical procedure used to analyze the amniotic fluid inside the uterus to detect fetal abnormalities. It is usually performed during the second or third trimester of pregnancy to provide accurate results. The procedure involves inserting a needle into the uterus and collecting the amniotic fluid for testing.
