Pharmacogenomic Testing — NAMI / American Association of Psychiatric Pharmacists

Pharmacogenomic testing examines how a person’s genes may affect their response to certain medications, including medications used to treat mental illness. This resource explains how testing is performed, what results may show, and how that information can support discussions with a prescriber. It describes potential benefits and limitations, including why testing cannot diagnose a mental illness or guarantee which medication will work best. Readers learn that medication history, other health conditions, and drug interactions also influence treatment decisions. Cost and insurance considerations are discussed, along with the importance of consulting a provider before changing medications. The information can help individuals and families prepare questions and develop realistic expectations about testing.
