Yeah the cheek swabs are real but there is no evidence to guide their use in day-to-day clinical settings. It's still basically a research tool. So I think this clinician is acting with a lot more confidence than he should be given the current state of scientific knowledge about psychiatric pharmacogenomics. That's unethical. He needs to tell patients that they are essentially participating in research, that this is not the standard of care in the profession and certainly as long as this is not the accepted treatment, neither patients nor their private insurance should be paying to have research done on them.

Regardless, I absolutely agree that the OP needs a T who can be present and provide the support and care they need. To me, the fact that this doctor has failed to set up his client with more support-- despite ample evidence that she needs it-- further suggests that this clinician is not meeting his ethical obligation.

From the second of the above-cited articles:

“I think the way to get the best quality evidence is to begin the study with groups of patients who are genotyped at the front end, so we know who is a slow metabolizer and who is likely to respond to one drug or not,” Mrazek said. “These studies are just beginning to be done.” - See more at: Psychiatric Pharmacogenomics | Psychiatric Times
