The impression I get is the biology is so messy that, even if that passed an ethics committee, they would still have difficulty isolating the stuff they were interested in from other effects they couldn’t control for.
It’s not impossible, but it is very expensive. This is partly why medical tech takes about 10-15 years to go from invention to deployment.
Why would a blood analysis be difficult to get pass an ethics committee? I get the confounding factors bit, but blood analysis seems to be a common practice.
