The author is shocked shocked to find out that in the USA just like in any other civilised country if you give out medical advice you have to be licensed and if you have a device that gives out medical advice the FDA has to ensure that the device works correctly. And no, it is not going to be much different in Singapore either. I read the newsweek article and if those genetic tests do what the regulator says they do (i.e., if they actually tell you which drugs you are genetically predisposed to), then that is certainly medical advice with very important practical implications (and also potential disasters if the advice is wrong), so the device makers should show to the FDA that their devices actually work.
