Quick Answer: GeneSight testing is a pharmacogenomic test that looks at genetic variations that may affect how your body metabolizes or responds to certain psychiatric medications. The results can give your prescribing clinician additional information when considering medication selection or dosing, but the test can’t guarantee which medication will work best for you.
Choosing a psychiatric medication can feel frustrating when you’ve already tried one or more medications without the results you hoped for. Genetic testing can offer another piece of information to consider, particularly when medication response or side effects have been difficult to predict.
At Saltwood Mental Health, we consider GeneSight results alongside your symptoms, treatment history, current medications, and goals.

What Is a GeneSight Test, and How Does GeneSight Testing Work?
GeneSight testing uses a DNA sample, typically collected through a cheek swab, to evaluate genes associated with how the body processes or responds to certain medications. The sample is analyzed by a laboratory, and the results are provided to the ordering clinician in a report.
Certain genetic variations can affect enzymes involved in drug metabolism. For example, variations involving CYP2D6 and CYP2C19 can influence the metabolism of some antidepressants, which may be relevant when clinicians consider medication selection or dosing.
What GeneSight Testing Looks For
GeneSight testing looks for genetic differences that may influence a medication’s metabolism or response. The test includes information related to several categories of psychiatric medications, including antidepressants, antipsychotics, anxiety and sleep medications, mood stabilizers, and certain ADHD medications.
This information doesn’t replace your symptoms, diagnosis, medication history, other prescriptions, physical health, or previous treatment response. We view genetics as one part of a larger clinical picture.
What Do the GeneSight Color Categories Mean?
The GeneSight report organizes medications into three color-coded categories based on identified gene-drug interactions. These categories make the results easier for clinicians to interpret.
➤ Green — Use as Directed: No identified genetic issues are expected to substantially alter outcomes based on the test.
➤ Yellow — Moderate Gene-Drug Interaction: Genetic factors may suggest that dosage changes or additional consideration could be appropriate.
➤ Red — Significant Gene-Drug Interaction: Genetic factors are expected to have a greater potential impact on how the medication is processed or tolerated.
A medication appearing in the green category isn’t guaranteed to work, and a medication appearing in the red category isn’t automatically inappropriate. The report is meant to support clinical decision-making, not replace it.
Can GeneSight Tell You Which Medication Will Work?
GeneSight cannot definitively tell you which psychiatric medication will be most effective. Medication response depends on far more than genetics, including diagnosis, age, other medications, medical conditions, lifestyle factors, environment, and individual biology.
The FDA recognizes that pharmacogenetic information can sometimes help clinicians consider therapeutic strategies or dosing, but genetic results need to be interpreted alongside other patient-specific information.
Who Might Consider GeneSight Testing?
GeneSight testing may be worth discussing when medication decisions have been difficult or when additional clinical information could help guide treatment. Someone who has experienced troublesome side effects, limited improvement, or several previous medication trials may want to ask a psychiatric provider whether testing could be useful.
Testing isn’t necessary for every patient. We evaluate whether it is likely to provide meaningful information based on the individual situation.
GeneSight Testing and Antidepressants
Information provided by pharmacogenomic testing can be particularly relevant for certain antidepressants because some medications are metabolized by enzymes influenced by genetic variation. Clinical pharmacogenetic guidelines include gene-based recommendations for selected antidepressants involving genes such as CYP2D6 and CYP2C19.
That doesn’t mean genetics determines whether an antidepressant will succeed. It means genetic information may provide another data point when a clinician is considering medication choice, dosage, or monitoring.
