We deliver more than just a lab test—we offer medically actionable insights backed by expert lab science.
Texas Diagnostics Labs partners with providers to ensure PGx results are not only accurate but easy to interpret and apply in real-world care. We focus on clarity, compliance, and communication—making it easier for doctors to act on your results.
Avoid side effects, skip the guesswork, and find what actually works.
Your DNA can influence how your body breaks down medications, which can affect how well a drug works—or if it’s even safe.
Without PGx testing, doctors may need to try multiple medications before finding one that works. This process can take weeks or months, and cause unnecessary side effects. With a PGx report in hand, your provider can make informed decisions quickly—targeting treatments that are most likely to help, and avoiding those that could cause harm.
Fast, non-invasive, and easy to complete from home or at your provider’s office.
All it takes is a cheek swab to unlock powerful medication guidance based on your genetics.
After collecting a DNA sample using a swab, you simply return it using the provided kit. Our lab analyzes the sample and delivers a detailed report to your healthcare provider. You’ll receive clear results that can guide current and future medication decisions—especially if your health needs change.
