Details and patient eligibility


Determine if antidepressant treatment guided by pharmacogenetic algorithm and interpretive report improves outcomes when compared with standard treatment without the availability of genetic information.

Full description

This study is designed to evaluate the clinical impact of pharmacogenetic (PGx)-directed treatment, as guided by interpretive, algorithmic report in the Pine Rest outpatient behavioral health clinics. The PGx algorithm utilized in this study is the foundation of a novel method of interpreting genetic testing results and reports them in a rapidly delivered format that provides enhanced guidance to psychiatrists in their selection of antidepressant medications


50 patients

  • The patient is an outpatient and not in imminent need of inpatient hospitalization for medical or psychiatric reasons.
  • Patient's baseline 17-Item Hamilton Depression (HAMD17) Rating score is >14.
  • Provide a copy of a physical exam report performed within 6 months prior to study enrollment or undergo a physical exam by either their personal physician, a physician who is a subinvestigator on the study, or a study-contracted physician assistant in internal medicine.
  • Undergo a medical history that includes a review of major organ systems by either their treating clinician, a subinvestigator physician, or a study-contracted physician assistant in internal medicine.

  • History of prior pharmacogenomic testing.
