Prequel Prenatal Screening Test High Rate of False Positives Class Action

Myriad Genetics, Inc. offers a Prequel Prenatal Screen for pregnant women that purports to screen for chromosomal and genetic conditions that may affect the baby’s health. But the complaint for this class action alleges that the test is very inaccurate, with its indications of a genetic disorder being false as much as 85 percent of the time. The complaint alleges that the tests are worth less than they cost and that they may subject mothers-to-be to unnecessary counseling, further testing, and even possibly the termination of a viable pregnancy.

The Nationwide Class for this action is all persons in the US who bought a Prequel Test. A California Subclass has also been proposed for all persons in the above class who live in California.

Many expectant parents would like to have prenatal testing done, and in recent years, noninvasive types have been offered, including something called Non-Invasive Prenatal Testing (NIPT).

The complaint alleges, “NIPT analyzes DNA fragments from the blood of a pregnant [woman] to estimate the risk that the fetus will be born with certain genetic abnormalities, including chromosomal disorders like Down Syndrome and Trisomy 18, or other, [rarer] disorders, like Prader-Willi and Angelman Syndrome.”

Unfortunately, the complaint claims, these tests have high rates of false positives. It refers to a January 2022 New York Times article to assert, “Prequel Test results indicating a genetic disorder are incorrect approximately 85 percent of the time.” In other words, the complaint claims, out of every 100 positive results indicating a disorder, 15 are correct and 85 are incorrect, indicating the fetus has a disorder that it does not in fact have.

According to the complaint, Myriad advertises its tests as reliable, accurate, and offering expectant parents peace of mind. The complaint quotes Myriad as saying that its test “has the lowest test failure rate in the industry, which translates to a lower chance of needing a repeat test or an unnecessary invasive diagnostic procedure.” It further claims Myriad says that the tests are “more accurate than maternal serum screening” and will “reduc[e] the chances you’ll need an unnecessary invasive follow-up test.”

The plaintiff in this case, Ashley Carroll, paid $295 for her test.

But the complaint claims the tests are not very accurate at all. Instead, it alleges, “as a result of these false results, expecting mothers are often unnecessarily subjected to further diagnostic testing, genetic counseling, and even the erroneous termination of a viable pregnancy.”

The counts include breaches of warranties, fraudulent omission, and fraudulent concealment, and false advertising, among other things.
