Arm Intervention/treatment
Active Comparator: GeneSight Psychotropic Tested
Subjects being tested with GeneSight Psychotropic
Genetic: GeneSight Psychotropic

The GeneSight Psychotropic product is a pharmacogenomic decision support tool that helps clinicians to make informed, evidence-based decisions about proper drug selection, based on the testing for clinically important genetic variants in multiple pharmacokinetic and pharmacodynamic genes that affect a patient's ability to tolerate or respond to medications.

The GeneSight Psychotropic product contains the most commonly prescribed antidepressant and antipsychotic medications, including a full representation of the SSRI and SNRI drug classes.

tricyclic antidepressants, an MAOI, and typical and atypical antipsychotics are also represented.

Other Names:
  • Assurex Health
  • GeneSight

Placebo Comparator: Treatment As Usual
This group of subjects will not see their GeneSIght results or know whether or not they are in either arm.

  • Anticipated inability to attend scheduled study visits;
  • Patients who in the judgment of the Investigator may be unreliable or uncooperative with the evaluation procedure outlined in this protocol;
