For this test to become mainstream it would A.) save lives and B.) save the VA probably billions in dollars in overmedication costs, and yet they’re not doing it and it’s like leaving your brothers out to dry, the overwhelming consensus of the pharmacogenomic community is that most of these tests currently lack evidence of clinical effectiveness. That means they have not shown to have better outcomes over the usual methods of drug prescription, with some exceptions. Many commercial tests target psychiatric disease therapy and pain management. One recent VA review documented that these tests do not yet have evidence for utility, especially in the veteran population.
