Dan Robitzski names a number of DNA testing firms and outlines how questionable their results are, writing, in part:
The problem, according to experts, is that these companies are promising information about DNA with a granularity that even scientists can’t deliver. Deanna Church, a geneticist at the biotech company Inscripta, told Futurism the tests are “all equally useless.”
“There is not a scientific basis for this sort of testing,” she said. “I certainly would not recommend anyone spend any money on this sort of thing.”

This can cause problems — Genomelink customers could feasibly see their predictions for traits like “gluten sensitivity,” “longevity,” or “alcohol drinking behavior,” assume the results are valid, and make ill-informed lifestyle or medical changes based on the results.
And other Genomelink customers agree with Mary: the results just don’t hold up.
