Amniocentesis is a process by which amniotic fluid (fluid present inside the uterus surrounding the unborn baby) from the uterus of a pregnant lady is taken out by a needle to test the developmental abnormalities of the baby inside the mother's womb. This test can detect genetic disorders like thalassemia, Down's syndrome, anemia, and many other abnormalities before birth.
