Genetic tests promised to help me achieve peak fitness. What I got was a fiascoThis is an excellent article. The author took a lot of time to compare genetic testing products from different companies and the recommendations they make based on the results. Although this article is about a year and a half old, it's clear that these products have not developed to the point where they are truly useful. I think there is a lot of potential, but it'll take some time for the science to develop to the point where these tests become useful.
But among the scores of data points, I found 20 genetic variants that showed up on two or more test results. The companies all gave me the same genetic readout on those variants, so I have little doubt they correctly analyzed the cells in the cheek swab I’d sent them. In six cases, however, the interpretation I got from one company directly contradicted the interpretation from another.
And in one case, two companies cited the same journal article to support their opposing conclusions.
