NIPT tests (noninvasive prenatal testing) uses a pregnant person’s blood to detect congenital abnormalities in the fetus’s DNA. The DNA is examined for genetic conditions. NIPT tests don’t diagnose conditions. They tell your provider how likely it is that a condition exists. This test can be done beginning at 10 weeks of pregnancy. NIPT is about 99% accurate in detecting trisomy 21. This test is the most accurate screening test for genetic conditions. If it shows high risk, further evaluation amniocentesis should be offered by your doctor to diagnose the condition.
