Starting or adjusting psychiatric medication is often described as a process—but for many people, it doesn’t feel like progress. It can feel like waiting. Waiting to see if something works. Waiting to see if side effects settle. Waiting to feel like yourself again. You may have tried more than one medication already, only to find that the results were inconsistent or difficult to tolerate. Sometimes there’s partial relief, but not enough to feel stable. Other times, the side effects outweigh any benefit, and you’re left deciding whether to continue or start over.
Over time, this pattern can become exhausting. Each change can feel like a reset rather than a step forward. It’s not uncommon to begin questioning whether the right medication exists for you at all. In reality, your response to medication is influenced by factors that aren’t always visible in a standard evaluation—how your body metabolizes certain drugs, how your nervous system responds, and how your biology interacts with treatment. At Willow & Stone, we approach this differently. Instead of continuing to adjust medications without clear direction, we look for data that can help guide those decisions more precisely. Genetic testing is one way we begin to bring that clarity into the process.
GeneSight testing is a form of pharmacogenomic testing used to better understand how your body processes and responds to certain psychiatric medications. It’s done with a simple cheek swab, but the information it provides goes beyond what we can typically see in a standard evaluation. Instead of relying only on symptoms and past medication history, it looks at how your genetics may influence the way specific medications are metabolized and tolerated.
In practical terms, this helps explain why one medication may work well for one person and not for another. Some individuals metabolize medications quickly, meaning a drug may not stay in the system long enough to be effective. Others metabolize more slowly, which can increase the likelihood of side effects even at lower doses. These differences aren’t something you can feel or predict—they’re part of your underlying biology. GeneSight testing brings that information into view so treatment decisions are not based on guesswork alone.
The results organize medications into categories that reflect how your body is likely to process them. This doesn’t replace clinical judgment, and it doesn’t automatically determine the “right” medication. What it does is give us a clearer starting point. Instead of cycling through options without direction, we can make more informed choices about which medications may be easier for your body to handle and which may need a different dose, closer monitoring, or a different choice.
At Willow & Stone, we use GeneSight testing as part of a broader, integrative approach. It’s one piece of the picture—but an important one. When combined with a detailed clinical evaluation, your history, and other biological factors, it allows us to approach medication management with more precision and less uncertainty.
In most psychiatric care settings, medication decisions are made based on diagnosis, symptom patterns, and general prescribing guidelines. While this is a standard and often necessary approach, it doesn’t account for the biological differences that influence how each person processes medication. Genetics play a meaningful role in how quickly some medications are broken down, and so how much of a drug stays in your system and how likely it is to cause side effects. These differences aren’t visible during a routine evaluation, which is why two people with similar symptoms can have completely different responses to the same medication.
This is where the trial-and-error experience often begins. A medication may be clinically appropriate on paper, but your body may process it in a way that limits its effectiveness or increases unwanted effects. Adjustments are made, doses are changed, or new medications are introduced, often without a clear explanation for why the previous option didn’t work. Over time, this can feel frustrating and unpredictable. By incorporating genetic insights into the process, we’re able to better understand these patterns and reduce the amount of guesswork involved in finding a medication plan that fits your biology.
GeneSight testing isn’t necessary for every situation, but it can be especially helpful when medication treatment has felt inconsistent, frustrating, or unclear. Many of the patients we see are not starting from scratch—they’ve already tried one or more medications and are looking for a more informed way forward. This is where genetic insight can change the direction of care.
If you’ve tried multiple antidepressants with limited improvement, it’s reasonable to ask why. In some cases, the issue isn’t the diagnosis—it’s how your body is processing the medication. GeneSight testing can help identify whether certain medications are less likely to be effective based on your metabolism, allowing us to consider options that may be better aligned with your biology.
Side effects are one of the most common reasons people stop or avoid medication altogether. Feeling overly sedated, restless, emotionally flat, or physically uncomfortable can make it hard to stay consistent with treatment. Genetic testing can provide insight into whether your body processes certain medications more slowly, which may increase the likelihood of side effects even at standard doses.
Anxiety treatment can be particularly variable. Some medications provide relief quickly, while others may have little impact or even increase symptoms. When anxiety remains persistent despite appropriate treatment, it often signals that a different approach is needed. GeneSight testing helps narrow down which medications may be more suitable, reducing the need for repeated adjustments.
If you’ve gone through several medication changes without a clear pattern of improvement, it can start to feel like there’s no consistent direction. Each adjustment may bring temporary hope, followed by uncertainty. Genetic testing introduces a level of clarity by helping us understand how your body is likely to respond before making another change.
Finding the right medication for attention-related concerns can take time, especially when responses vary widely between individuals. Some people experience minimal benefit, while others struggle with side effects that make the medication difficult to continue. GeneSight testing can offer additional insight into how stimulant and non-stimulant medications may be processed, helping guide more precise treatment decisions.
For patients in these situations, GeneSight testing doesn’t replace clinical care—it strengthens it. It allows us to move forward with more information, more intention, and a clearer understanding of how your body may respond to treatment.
GeneSight results are designed to be practical and clinically useful. Rather than overwhelming you with raw genetic data, the report organizes information in a way that helps guide real treatment decisions. It gives us a clearer sense of how your body is likely to process certain psychiatric medications and where we may want to be more thoughtful in our approach.
One of the most recognizable parts of the report is the medication grouping system. Medications are placed into categories based on how your body may metabolize them. Some fall into a range that is generally more compatible, while others may require adjustments or closer monitoring. This doesn’t mean a medication is automatically ruled in or out, but it does help us prioritize options and avoid unnecessary trial-and-error when possible.
The results also provide insight into metabolism—how quickly or slowly your body processes specific medications. This can explain patterns like why a medication felt ineffective at standard doses, or why side effects showed up more strongly than expected. In some cases, it may guide decisions around dosing, timing, or whether a different medication would be a better fit.
Side effect considerations are another important part of the report. Certain genetic variations can increase the likelihood of sensitivity to specific medications. Having that information ahead of time allows us to plan more carefully, rather than reacting after side effects occur.
At Willow & Stone, we don’t treat the report as a standalone answer. It’s one piece of a larger clinical picture. When we combine these results with your history, symptoms, and overall health, it allows us to make medication decisions with more clarity and intention, rather than relying solely on trial and adjustment.
The process for GeneSight testing is straightforward, but the value comes from how the results are used within your care. Each step is designed to move from simple collection to more informed decision-making, without adding unnecessary complexity to your treatment.
The test begins with a quick cheek swab, which can be done in the office or arranged for at-home collection. There are no needles, no fasting requirements, and no preparation needed. The sample is then sent to the lab for analysis.
Once received, the lab analyzes specific genes that influence how your body metabolizes and responds to psychiatric medications. GeneSight says results usually reach your clinician about three days after the lab receives the sample. The goal is not to diagnose a condition, but to understand how your biology may affect medication response.
When your results are ready, we review them together in the context of your full clinical picture. This includes your current symptoms, past medication experiences, and any side effects you’ve had. The report becomes part of a larger conversation, not a standalone recommendation.
Using both the genetic insights and your clinical history, we develop a more targeted approach to medication. This may involve selecting a new medication, adjusting a current one, or confirming that your current plan is appropriate. The goal is to move forward with more clarity and fewer unnecessary changes.
At Willow & Stone, the process is intentionally collaborative. GeneSight testing gives us better information—but how we use that information is what shapes your care moving forward.
GeneSight testing is not a standalone service or a separate track of care—it’s integrated into how we approach treatment as a whole. Within an integrative psychiatry model, medication decisions are not made in isolation. They are informed by multiple layers of information, including your clinical history, current symptoms, lifestyle factors, and when appropriate, lab data like genetic testing. GeneSight becomes one of those data points, helping us make more precise decisions about medication selection and dosing rather than relying on repeated adjustments without clear direction. It supports a more personalized approach, where treatment is guided by how your body is likely to respond, not just by general prescribing patterns.
GeneSight testing is often covered by insurance, and many patients find that out-of-pocket costs are lower than expected. Coverage can vary depending on your plan, but the testing company typically provides clear guidance on pricing before moving forward. For those without full coverage, financial assistance and payment plans are available to help make testing more accessible. If you have questions about cost, we can walk through what to expect so there are no surprises.
Medication decisions shouldn’t rely on guesswork alone. At Willow & Stone, we approach treatment with a combination of clinical experience and objective data, so decisions are grounded in more than just trial and response. GeneSight testing is one way we bring that clarity into the process, but it’s always considered alongside your full history, symptoms, and overall health. We look at how different pieces of your biology and environment interact, rather than isolating one factor at a time. This allows us to move more deliberately, with a focus on finding a treatment approach that is both effective and sustainable for you.
If medication has felt inconsistent or difficult to navigate, it may be time to take a more informed approach. GeneSight testing can provide additional clarity, helping guide decisions with a better understanding of how your body responds to treatment.
If you’re considering whether this is the right next step, we can talk through your history, your current concerns, and whether genetic testing would be useful in your care. There’s no pressure to move forward—just an opportunity to make decisions with more information and less uncertainty.
GeneSight looks at genes that affect how your body handles certain psychiatric medications, mostly the liver enzymes that break them down. That can explain a lot: why one antidepressant gave you strong side effects at a low dose, or why another seemed to do nothing. It also has real limits, and knowing them up front makes the results more useful.
You do not need to come into the office. The cheek swab can be collected at home and sent to the lab, and Dr. Forbes reviews the results with you by video or in person in Arlington. Telehealth care is available if you are physically in Texas, New Mexico, Florida, Alaska, Arizona or Colorado at the time of your visits. The test itself is billed by GeneSight, not by Willow & Stone. GeneSight says it contacts you before processing if your cost could be more than $330, and it offers payment plans and financial assistance. The step-by-step version, including what to do while you wait, is in getting a GeneSight test.
The report sorts medications into groups by how strongly your genes are expected to affect them. A medication in the most cautious group is not forbidden, and one in the least cautious group is not guaranteed to work; the grouping is about how your body is likely to handle the drug, not whether it treats your condition. Dr. Forbes goes through it with you line by line, alongside what you have already tried. If you want to understand it before that visit, read how to read your GeneSight report.
The genes on the report do not change, so the result stays relevant long after this round of treatment. Some of the same genes affect common medicines outside psychiatry, including certain pain medicines and heart medicines, which makes the report worth sharing with your primary care clinician and pharmacist.

Your result is part of your medical record and is protected like the rest of your health information. A federal law, the Genetic Information Nondiscrimination Act, also limits how health insurers and employers can use genetic information, though it does not reach every kind of insurance.

GeneSight is a pharmacogenomic (DNA) test that helps predict how you may respond to certain psychiatric medications, taking some of the guesswork out of prescribing.
No — it’s a guide, not a guarantee. Dr. Forbes combines the results with your full clinical picture to personalize prescribing.
A simple cheek swab, which can be arranged without an in-person visit; results are reviewed with you by telehealth.
Yes. The cheek swab can be collected at home, so no office visit is needed, and results are reviewed with you by video. Telehealth is available if you are physically in Texas, New Mexico, Florida, Alaska, Arizona or Colorado at the time of your visits.
Yes. Some medications, supplements and even smoking can speed up or slow down the same enzymes the test measures, so your body may act differently from what your genes alone suggest. That is why results are always read alongside everything you take.
Usually not. The genes tested do not change over your life. What can change is the science: newer panels test more genes and guidance gets updated, so keep a copy of your report and share it with every clinician who prescribes for you.
Your result is part of your medical record and is protected like other health information. A federal law, GINA, also bars health insurers and most employers from using genetic information against you, though it does not cover life, disability or long-term-care insurance.
Bring it. Consumer tests look at far fewer medication-related genes than a clinical panel and are not meant to guide prescribing on their own, but any prior report is useful context and helps decide whether a clinical test would add anything.
Willow & Stone provides integrative telehealth psychiatry to patients across Texas, New Mexico, Florida, Alaska, Arizona, and Colorado — from major metros to rural communities with few local providers.
