New VA study finds access to the GeneSight® test impacted treatment decisions and improved depression remission rates
Study design
The PRIME Care study is the largest pharmacogenomic (PGx) randomized controlled trial (RCT) ever conducted in mental health.
The study investigated whether access to genetic testing results impacted treatment decisions and improved patient outcomes for those with MDD (Major Depressive Disorder).
The study was conducted across 22 VA Clinics with 676 clinicians.
1,944 veteran patients with MDD received the GeneSight Psychotropic test and were randomized to receive results immediately (GeneSight test arm) or after 24 weeks (treatment as usual arm).
The study was funded by the U.S. Department of Veteran Affairs and Myriad Genetics provided the GeneSight tests.
Study results
What is the GeneSight Psychotropic test?
The GeneSight Psychotropic test is a genetic test that shows your healthcare provider how your genes may affect medication outcomes.
The GeneSight test may reveal which medications to treat depression, anxiety, ADHD, and other mental health conditions that:
- Require dose adjustments
- Be less likely to work
- Have an increased risk of side effects based on your DNA
Cost shouldn’t be a barrier to your mental wellness
Our goal is to make the GeneSight test affordable and accessible to patients.
Many insurance plans, including Medicare, often cover the entire or a significant portion of the test.
We offer a financial assistance plan for eligible patients to help with the cost of the GeneSight test.
If your cost is $100 or more, we offer an interest-free payment plan to spread out the cost for up to 12 months.
*Based on a review of six months of past claim data for major insurance carriers across the US. Last updated 2023.
How does it work?
The GeneSight test is administered by your healthcare provider in their office.
Order
The GeneSight test must be ordered by a prescribing clinician who is registered to offer the GeneSight test. This list includes but is not limited to primary care physician, nurse practitioner, physician’s assistant, and/or psychiatrist.
Collection
Your doctor collects a DNA sample by painlessly swabbing the inside of your cheek OR you can collect the sample at home using our patient collection kit.
Lab
The sample is sent to our lab for analysis.
Results
After we receive your sample, your doctor will typically get test results in about 3 days.
Consultation
Your doctor can contact our Medical Affairs team for a consultation. Your doctor can then review the results with you on your next visit.

A comprehensive report, personalized for you
The GeneSight test report may help you avoid multiple medication trials by providing information about which medications may require dose adjustments, be less likely to work, or have an increased risk of side effects based on your genetic information.
The report also includes information on how a patient’s smoking status may affect their body’s metabolism of certain medications.

- Use as directed
- Moderate gene-drug interaction
- Significant gene-drug interaction
The report classifies over 60 mental health medications into three categories.
The GeneSight test results do not provide information on disease diagnosis, medication allergies, drug-drug interactions, or which medications will work best.
