One cheek swab.
The end of trial and error.
Your genes decide how your body handles a medication: which dose lands, which one does nothing, which one makes you feel worse. Pharmacogenomic testing reads that once, at home.

A pharmacogenomic test from RPh Labs reads the genes that control how your body processes medication, so you and your prescriber know in advance which drugs are likely to work, which may need a different dose, and which are worth avoiding. The panel covers 240+ medications across mental health, cardiology, pain, oncology and more.
Collection is a single cheek swab at your kitchen table. Drop it in the prepaid mailer and our CLIA-licensed lab returns a clinician-ready report in about a week. Your DNA is analyzed once and the report stays useful for every prescription you are given for the rest of your life.

Why pharmacogenomic testing matters for your health
Medications don’t work the same for everyone. Your genetic makeup influences how you respond to a given drug, affecting both its effectiveness and its safety. Pharmacogenomic testing reads that profile once and shows how your body is likely to process each medication, so your provider can make better-informed decisions about your treatment plan.
The FDA lists a growing number of medications with known gene-drug interactions. See which ones we test for.
Why it matters
Drugs may affect us differently
Variations in genetic makeup, metabolism and overall health change how a medication behaves in your body, which is why a personalized drug-response test is the shortest path to something that actually works.
Personalized medication selection
Your genetic profile shows how your body metabolizes each drug, so your prescriber can choose the one most likely to work the first time.
Reduced risk of side effects
Knowing your genetic predispositions helps predict how you will respond, lowering the chance of a harmful reaction before the first dose.
Optimized dosage
Results point to the dose your metabolism can handle, avoiding the under-dosing and over-dosing that make treatment feel like guesswork.
Improved treatment outcomes
With PGx insight, providers make better-informed decisions, more successful plans, better symptom management and faster recovery.
Genetic testing for medication: how it works
Understanding your body’s genetic response to certain medications has never been easier. With the RPh Labs pharmacogenomic testing kit you get a personalized medication report without visiting a clinic, for $299.00. Here is how the process works.
Step 1
Sample collection
Order the kit online and collect your sample at home with a cheek swab. No needles and no appointments, with clear instructions and prepaid shipping included.
Step 2
Pack and drop
Seal the swab in the biohazard bag, place it in the return mailer and drop it at the courier location on the label. It comes straight to our lab.
Step 3
Accredited lab analysis
Our CLIA-licensed lab runs a DNA analysis on clinically validated genes covering 240+ commonly prescribed medications.
Step 4
Personalized report
Within 7 to 10 business days your medication compatibility report lands in your secure account, in plain language you and your prescriber can use.
Step 5
Expert clinical support
Our clinical pharmacists and genetic counselors walk you through the results one-on-one and help optimize your treatment plan.
Precision prescribing powered by your DNA
Our pharmacogenomic testing report translates complex molecular data into a clear, actionable roadmap for personalized medication management. By analyzing your unique genetic makeup, we provide the insight needed to optimize treatment and reduce the risk of adverse drug reactions.
Actionable risk stratification
Instantly see which medications are safe to use and which require caution through an intuitive, color-coded summary, so you and your provider can quickly decide when to adjust a dose or consider an alternative therapy.
Multifactorial safety analysis
The review goes beyond genetics to include clinically significant interactions with other drugs, foods and organ function for a full view of patient safety that accounts for outside influences like grapefruit juice.
Comprehensive clinical coverage
Deep-dive insights across cardiology, psychiatry, pain management and immunology. Every report is aligned with FDA sources and professional guidelines for evidence-based care.
Expert clinical support
Every report includes access to licensed PharmD experts for provider consultations and genetic counselors for patient guidance, so molecular findings translate into confident decisions.

Frequently asked questions
Questions about our at-home pharmacogenomic test kit?
We have gathered the questions we hear most often about RPh Labs right here. If you do not see your answer, reach out and our team will help.
What is PGx testing?
Pharmacogenomic testing, also called pharmacogenetic testing or a PGx test, is a genetic test for drug compatibility. It reads the genes that control how your body processes medication so your prescriber can choose the right drug and dose the first time.
Which states are covered by RPh Labs?
We ship our at-home pharmacogenomic test kit nationwide and our CLIA-licensed lab accepts samples from patients across the United States. A few states have additional requirements for direct-to-consumer testing, and our team will let you know at checkout if yours is one of them.
Is PGx testing only for prescription drugs?
The panel focuses on prescription medications across mental health, cardiology, pain management, oncology and more, but the report also flags clinically significant interactions with over-the-counter products, supplements and foods.
Do PGx tests help prescribe the best mental health medications?
Yes. Psychiatry is one of the most studied areas in pharmacogenomics. The report shows how you are likely to metabolize common antidepressants, antipsychotics and mood stabilizers, which can shorten the trial and error period considerably.
Can I pay for my PGx test in installments?
Installment payment options are available at checkout through our payment provider, so you can spread the cost over several months with no impact on how quickly your kit ships.
Does RPh Labs accept HSA and FSA payments?
Yes. The kit is HSA and FSA eligible, and you can pay with your benefits card directly at checkout. We provide an itemized receipt if your plan requires documentation.
Why should I choose RPh Labs for PGx testing?
For pharmacogenomic testing you can rely on, your sample is processed in a CLIA-licensed, COLA-accredited laboratory, the report is reviewed against FDA sources and professional guidelines, and every order includes one-on-one time with a licensed PharmD or genetic counselor.
Is PGx testing covered by insurance?
Coverage varies by plan and diagnosis. Many patients pay directly using HSA or FSA funds. If your plan may cover testing, we can supply the documentation you need to submit a claim.
How long does it take to get my results?
Most reports are ready within 7 to 10 business days of your sample arriving at the lab, and they are delivered to your secure online account with an email notification.
