Pharmacogenomics (PGx) Testing
How to Understand Your Test Results


Your PGx test was performed by Preventive Genomics using a simple cheek swab.

This test looks at how your genes affect the way your body responds to certain medications.

Simple Summary for Patients

Pharmacogenomics (PGx) studies how your DNA influences:

  • How fast or slow your body breaks down medications
  • How well a medication may work for you
  • Your possible risk for side effects

Because everyone's genes are different, the same medication can affect people differently.

Your report classifies how you process certain medications using terms like:

  • Normal (Extensive) Metabolizer – Medication is processed at an expected rate
  • Intermediate Metabolizer – Medication may stay in your body longer
  • Poor Metabolizer – Higher risk of side effects for some medications
  • Ultrarapid Metabolizer – Medication may be cleared too quickly to work well

These results help your healthcare provider decide whether:

  • A standard dose is appropriate
  • A lower or higher dose may be needed
  • A different medication may be safer or more effective

Your report may include medications used for:

  • Pain management
  • Blood pressure and heart conditions
  • Cholesterol
  • Blood thinners
  • Depression and anxiety
  • Diabetes
  • Stomach and reflux conditions
  • Respiratory conditions
  • This test does not diagnose any disease.
  • It does not guarantee how you will respond to a medication.
  • Other factors (age, kidney function, other medications) also affect drug response.
  • Always speak with your doctor before making any medication changes.

Your genetic makeup does not change over time.
That means this information can help guide medication decisions throughout your life.


This test supports a more personalized approach to your healthcare — helping your provider choose medications that may be safer and more effective for you.


If you have questions about your results, please discuss them with your prescribing physician or pharmacist.
