Pharmacogenetic Testing Among Patients With Mood and Anxiety Disorders Is Associated With Decreased Utilization and Cost: A Propensity-Score Matched Study

We sought to examine the relationship between a commercial pharmacogenetic test for psychotropic medications and 6-month cost of care and utilization in a large commercial health plan.
