Quick Answer: Pharmacogenetic testing looks at inherited genetic differences that may affect how your body processes or responds to certain medications. In mental health care, the results can give clinicians additional information when considering some psychiatric medications, including certain antidepressants.
Finding a psychiatric medication that works well can take time, especially when you’ve experienced side effects or limited benefit from previous medications. Pharmacogenetic testing in Dallas, Texas, can provide additional information about how your genetics may influence your response to certain medications.
At Saltwood Mental Health, we use genetic information as one part of a broader treatment decision, not as a substitute for understanding your symptoms and history.

How Pharmacogenetic Testing Works
Pharmacogenetic testing looks for specific genetic variations that can influence how medications are metabolized in the body. Testing is usually completed with a cheek swab or saliva sample, although some laboratories may use a blood sample.
The laboratory then analyzes genes associated with medication metabolism and response. Your clinician can use those findings as one piece of information when evaluating medication options.
What Pharmacogenetic Tests Can Tell You
Pharmacogenetic testing can show whether your genetic profile may cause you to process certain medications differently from another person. Some people metabolize a medication more slowly, while others may process the same medication more quickly.
For example, if your body breaks down a particular antidepressant very slowly, you could experience higher medication exposure at a standard dose. If you metabolize it very quickly, drug levels may be lower than expected. Depending on the medication, this information may influence dosing, monitoring, or whether another option should be considered.
Genes such as CYP2D6 and CYP2C19 help determine how quickly your body processes many medications. Testing these genes can therefore give your provider additional information to consider when evaluating certain psychiatric medications.
Can Pharmacogenetic Testing Help Choose an Antidepressant?
Pharmacogenetic testing can help guide the use of certain antidepressants, but it can’t identify a guaranteed “best antidepressant” for an individual. Its usefulness depends on whether there is meaningful clinical evidence connecting a particular gene to the medication being considered.
Clinical pharmacogenetic guidelines include gene-based recommendations for certain antidepressants. Depending on a person’s genetic profile, those recommendations may involve dose adjustments, closer monitoring, or consideration of an alternative medication.
This is why we view testing as a clinical decision-making tool rather than a medication-matching shortcut.
What Pharmacogenetic Testing Can’t Tell You
Pharmacogenetic testing can’t predict with certainty whether a psychiatric medication will work or whether you will experience a specific side effect. It also can’t diagnose depression, anxiety, bipolar disorder, ADHD, or another mental health condition.
Genetics are only one part of medication response. Your diagnosis, other medications, medical conditions, age, substance use, sleep, lifestyle, previous treatment experiences, and individual biology can all influence how you respond.
A report that places medications into different categories should therefore never be interpreted as a simple list of “good” and “bad” medications.
Who May Benefit From Pharmacogenetic Testing?
The benefits of pharmacogenetic testing may be most relevant for people who have had difficulty finding an effective or tolerable psychiatric medication. Testing may also be considered when someone has experienced significant side effects, several unsuccessful medication trials, or an unusually complicated medication history.
Pharmacogenetic testing isn’t equally useful for every medication or situation. When there is no well-established relationship between the medication being considered and the genes being analyzed, testing may provide limited additional information. We consider your medication history and treatment needs to determine whether the potential benefits of pharmacogenetic testing are likely to meaningfully inform your care.
Is Pharmacogenetic Testing Accurate?
Pharmacogenetic testing can accurately identify many of the genetic variants included in a laboratory’s test, but the clinical meaning of those results varies. Identifying a genetic variation is different from predicting exactly how someone will respond to a medication.
The strongest pharmacogenetic information comes from gene-medication relationships supported by established clinical evidence and prescribing guidance. As research evolves, recommendations may also change.
How Pharmacogenetic Testing Fits Into Psychiatric Care
Pharmacogenetic testing should complement a comprehensive psychiatric evaluation rather than replace one. The most useful medication decisions are made by combining relevant test results with clinical judgment and a detailed understanding of the person receiving care.
At Saltwood, we look at the complete picture: what you’re experiencing now, what has and hasn’t worked before, how medications have affected you, and what you want treatment to help you accomplish. That broader context is essential whether genetic testing is used or not.
Where Can You Get Pharmacogenetic Testing?
Pharmacogenetic testing is available through certain psychiatric providers, mental health clinics, and specialized laboratories. At Saltwood Mental Health, we can incorporate pharmacogenetic testing into care when appropriate and interpret the results alongside your symptoms, medication history, and treatment goals.

Personalized Mental Health Treatment at Saltwood
Finding the right psychiatric treatment can require more than simply trying another medication and waiting to see what happens. We believe patients deserve careful evaluation, clear explanations, close follow-up, and treatment decisions that are tailored to their individual needs.
At Saltwood Mental Health, our team provides elevated outpatient mental health care for adults who may need more structure and support than traditional weekly appointments alone can provide. When appropriate, pharmacogenetic testing can become one part of a more comprehensive medication and treatment strategy.
If medications haven’t worked as expected, side effects have made treatment difficult, or you’re looking for a more individualized approach to mental health care, contact Saltwood Mental Health today.
We can help you understand your options and develop a treatment plan built around you—not simply your diagnosis.
