Many people explore a genetic test for antidepressants after a frustrating cycle of trying medication after medication. Pharmacogenomic (PGx) testing — sometimes described as a mental health medication genetic test — doesn't pick your medication. What it can do is report gene variants associated with how your body may process certain psychiatric medications, providing information that may help you and your prescriber evaluate options.
Your body processes medications using pathways partly determined by your genes. Variants in genes involved in drug metabolism are associated with differences in how quickly some medications are broken down, which can relate to how people experience them. For antidepressants and some anxiety medications, this is one of the better-studied areas of PGx research — though evidence strength varies by medication, and response is also shaped by age, health conditions, other medications, and environment.
The most valuable use of a PGx report is as a conversation starter with the professional who prescribes your care. Bring your results, your current medication list, and your questions — for example, whether any findings relate to medications you take today or may consider later. Your prescriber can weigh the report against your diagnosis, history, and treatment goals.

Important: Pharmacogenomic (PGx) testing provides information about how genetic variations may influence an individual's response to certain medications. Results are intended to support, not replace, the judgment of a qualified healthcare professional and should not be used to diagnose, treat, cure, or prevent any disease. Do not start, stop, change, or adjust any medication based solely on PGx test results. Always consult your physician, pharmacist, or other qualified healthcare provider before making medication or treatment decisions. PGx results do not guarantee that a medication will be effective, ineffective, or free from side effects.
