A couple of points. The 23andme no longer banned in the US, since they have toned down many of the claims. Although the FDA letter to 23andMe was pretty full on.
Also it’s not really a full diagnostic test, it’s more of a lifestyle screen that has some element of prediction risk since there is a fair amount of subjectivity to interpreting the results. It was widely reported a few years ago, when journalists send their DNA to a few different labs, they got quite widely different interpretation of their results.
The serious stuff (cancer predisposition, late on-set disorders) have all been removed from the current test.
I work in genetic diagnostics and would I use it – no. Either go for a proper test or save you £125 (btw it’s $99 in the US)
