How accurate is NIPT?

NIPT is more than 99% reliable for the detection of most common trisomies (Down, Edwards, and Patau syndrome).¹ By comparison, traditional blood tests can miss
as many as 15% of cases in pregnant women.

NIPT is also much less likely than traditional tests to give you a false-positive result, meaning there is much less chance your doctor would recommend follow-up invasive testing, such as amniocentesis.

NIPT is a screening test which means that all high-risk results should be confirmed with diagnostic testing.
