Natera Prenatal Tests High Rate of False Positives Complaint

February 17, 2022

Natera, Inc. offers noninvasive prenatal tests (NIPTs) that can help alert pregnant women to chromosomal disorders in the fetus, such as Down syndrome. Natera advertises these tests as being the most reliable available. But the complaint for this class action alleges that Natera’s tests, while effective for screening for Down syndrome, give a high number of false positives for other conditions. The complaint alleges they are “incorrect 85 percent of the time or more—up to 98 percent.”
