Pharmacogenomic Testing


This is a test that analyzes how your DNA may affect your response to depression medications. The results of the test can help your doctor prescribe a more genetically optimal medication and avoid medications that may cause side effects or be less likely to work.

We use GeneSight for the Pharmacogenomic Testing and over 1 million patients have taken this test.

If you have been diagnosed with depression and failed at least one medication, consider talking to your doctor about this test.

The pharmacogenomic test analyzes clinically important genetic variations in your DNA. The results of the test can inform your doctor about genes that may impact how you metabolize or respond to certain medications.

There was an 8 week, blinded, multi-center, randomized controlled trial of 1,167 subjects with major depressive disorder from 20 academic sites and 40 community sites. The trial was unblinded after the 8-week check-in, and the subjects were followed out to 24 weeks. The key findings were that

Switching to a medication with no or moderate gene-drug interactions improved patient outcomes: Symptom improvement, response, and remission were significantly improved when patients on medication with significant gene-drug interactions were switched to a medication with no or moderate gene-drug interactions.

Frequently Asked Questions (FAQ's) on Pharmacogenomic Testing

1. What is a pharmacogenomics?

Pharmacogenomics is a field of research that studies how a person’s genes affect how he or she responds to medications. This type of testing may help inform healthcare providers’ medication selection and dosing. While it cannot confirm which medications or doses will work for a patient, it can point out potential issues with medications.

Pharmacogenomics uses information about a person’s genetic makeup, or genome, to choose the medication and dosage that are likely to work best for that person.

2. What is GeneSight?

Genesight is a pharmacogenomic test that helps to analyze clinically important information in your DNA that can help your doctor understand which medication will work best for you.

3. Is the GeneSight test a pharmacogenomic test?

Yes, the GeneSight test is the leading pharmacogenomic test to help clinicians make better-informed decisions about medication selection to treat mental health conditions. Its technology is backed by extensive research and supported by multiple clinical studies published in peer-reviewed journals.

4. How is the test administered?

The test is a simple swab of the inside of the cheek. The swab is then sent off to the lab, which will send a report of results two days after it is received.
