Amniocentesis is a prenatal test recommended for women experiencing high-risk pregnancies.

During amniocentesis, an extremely thin needle is inserted through the abdominal and uterine walls, guided by ultrasound. Nearly 15-20 ml of amniotic fluid is extracted and sent to a laboratory for chromosome and biochemical analysis. The test is typically conducted between week 15 to 20 of pregnancy when adequate fluid has accumulated. It usually takes around 2-3 weeks to receive the diagnostic results.
