Gender test questioned by more parents

The uproar about Acu-Gen’s Baby Gender Mentor continues. The test—advertised on the provider’s website as a “NEW Baby Gender Mentor Home DNA Gender Testing Kit”—is presumably based upon identifying a Y-chromosome in fetal-specific DNA obtained from a few dried drops of mother’s blood. If there’s a Y, the baby’s a boy; if there’s no Y, the baby’s a girl; if you’ve told them ahead of time you’re expecting twins, they can tell you whether you have one baby of each sex. The other possible options are not described in the publicity.

The provider claims 99.9% accuracy—comparing their test to their claim for 80% accuracy of sonograms—and guarantees a 200% refund [if you meet certain requirements]. Yes, I intended the print of that text to be smaller.

So, what’s the problem?  Increasing numbers of mothers are claiming that the test inaccurately predicted the gender of their infants—but not all these infants have been born yet, and the provider of the test states that ultrasound is not sufficiently accurate to challenge their test. So, no one knows whether any refunds have been made or whether any of the "errors" have had serious ramifications. 

According to the Science Magazine article that the provider claims provides the proof that the test works, “Food and Drug Administration approval is not needed as long as the blood sample goes to a lab and the test is sold as a service rather than as a kit. The provider’s website interchanges the words test and kit quite frequently; however, because the actual testing is not done by the person who supplies the blood (as for example with a pregnancy test kit or the at-home HIV-testing kit), the conclusion that this is a test, not a kit, is probably appropriate.

Meanwhile, a Canadian company has been offering a fetal DNA gender test for more than 2 years. Their marketing is low-key, however, and the test uses fresh blood from a woman 10 or more weeks pregnant—not the dried blood from a woman 5 or more weeks pregnant.  

If the only risk were incorrectly buying the “wrong” gender clothing, maybe we could just say, “buyer beware”. We can only pray that no one considers terminating a pregnancy based on this gender test. Meanwhile, according to National Public Radio a couple of months ago, "customers and scientists are raising questions about the accuracy of the widely publicized genetic test; customers have complained to the Federal Trade Commission, and at least one law enforcement agency is investigating a company that sells the test."
