Meet the patient
A 38-year-old teacher walks in carrying a glossy folder. She has been well for two years on sertraline 100 mg — back at work, sleeping, no relapse. A direct-to-consumer pharmacogenomics panel has painted sertraline red. She wants it stopped today, and she wants "the green one".[3][8]
Two exam questions just walked through the door with her. Do you obey the colour wheel? and what is a pharmacogenomic result actually for? Every paragraph below exists to answer both.[3][8]
You have read the opening of this topic. The complete unit — every section and its primary-source references — is part of the Psychiatry Fellowship fellowship atlas.
