If you've ever felt frustrated trying one psychiatric medication after another without relief, you're not alone. Finding the right treatment can take time—and multiple trials. At Brookhaven Psychiatry, we’re proud to offer GeneSight® pharmacogenomic testing, a simple tool that helps us choose medications that are more likely to work with your body, not against it.
What Is GeneSight?
GeneSight is a genetic test that analyzes how your unique DNA may impact your response to certain psychiatric medications. It provides your psychiatrist with a personalized report that highlights which medications may be more effective—or more likely to cause side effects—based on your genetic profile.
This type of testing is especially helpful for individuals struggling with:
Depression
Anxiety
ADHD
Bipolar disorder
PTSD
Other mental health conditions requiring medication management
How GeneSight Helps with Medication Selection
At Brookhaven Psychiatry, we believe in precision medicine—using the most up-to-date tools to deliver tailored care. GeneSight testing can:
✅ Reduce medication trial-and-error
✅ Minimize side effects
✅ Identify medications better suited to your genetic makeup
✅ Improve treatment outcomes faster
Although no test can guarantee success, GeneSight gives us valuable insight to help guide our choices—especially if you’ve had limited success with prior treatments.
What to Expect from the Test
Testing is quick and painless. We simply collect a cheek swab during your visit. Results are typically available within a few business days. Once your report is ready, we’ll go over it with you in detail and incorporate it into your personalized treatment plan.
Is GeneSight Covered by Insurance?
Many commercial insurance plans and Medicare cover GeneSight testing when medically appropriate. Our team will help you check your coverage and provide cost information before moving forward.
