Amniocentesis (also called amnio) is a prenatal test that takes amniotic fluid from around your baby in the uterus (also called womb). The fluid is tested to see if your baby has certain health conditions. A prenatal test is a medical test you get during pregnancy. Talk to your health care provider to see if amnio is right for you. Amnio is a diagnostic test. This means that it tells you for sure whether or not your baby has a health condition. This is different from a screening test that tells if your baby’s more likely than others to have a certain condition. If results of a screening test aren’t normal, you may want to have a diagnostic test like amnio to diagnose (find out) if your baby has a condition. Amnio results almost always are correct.
