Good input from Paxiled & specialmom. I’m not a Dr nor Psychiatrist , but did work in a Science & Medical-related field for many years (Pharmaceutical industry), so I think what happens with any kind of pre-screening testing is, you’re not dealing with ‘absolutes’, just probabilities. So if a test indicates you have a 65% chance a drug will work w/ minimal side effects, that still means there’s a substantial chance (35%) it won’t work for you. All it can do is MAYBE narrow down the choices a little. I think it’s worth trying, but just be aware that it’s not perfect. As always, every individual is different - one person can take a drug w/ minimal side effects, and someone else w/ nearly identical characteristics can’t tolerate it at all...
There have been in the far too many years I've struggled with mental illness more ways they claim enable them to tell which meds to give someone than I an count. EEG tests. Brain scans. Tests of liver metabolites. Blood type. And then no matter what the book they then write about it says, everyone who reports what the treatment was like with that person turns out to be good old trial and error. I don't know if this works or not, but none of the other ones did.
