What is PGx?

PGx is short for pharmacogenomics. Pharmacogenomics is the study of how genes (DNA) affect an individual's response to drugs. Each one of us responds to drugs in different ways. As a result, the drug that works for some may not work for others.

At Great Lakes Labs, our certified pharmacogenomic program is called PGx360. It is a comprehensive look at an expansive list of black box drugs and their effects on an individual's genetic make-up.

A simple check swab is utilized to collect the sample.

By analyzing an individual's DNA, medicine becomes more personalized and appropriate for the person being treated. Medication therapy management (MTM) becomes more direct and accurate.


Why take a PGx test

Anyone who has been prescribed medication or is considering a new prescription will want this test. Studies gathered by Coriell Institute of Medical Research, Federal Drug Administration (FDA), and the Centers for Disease Control show:

  • Almost 50% of medications taken are deemed ineffective
  • 4th leading cause of death in hospitals is due to adverse drug reactions
  • 20% of hospital re-admissions are due to adverse drug reactions
  • 2 million ER visits are due to adverse drug reactions

Not only will the test assist your clinician in making an informed decision on the best medicine but will also help determine the correct dose.


What happens during and after my test

  • The test takes approximately 3 weeks to complete
  • A confidential report will be sent to a verified email address
  • Once your report is received, in approximately one week our certified pharmacogenomic pharmacist will be reaching out to discuss the test results

PGx Frequently Asked Questions (FAQ)

What is pharmacogenomics (PGx)?

The study of how genes (DNA) affect an individual's response to drugs.

Why should I take a pharmacogenomics test?

PGx determines:

  • the way you respond to drugs
    • whether the drug helps or has no effect
    • whether a drug is likely to benefit you and be safe (adverse reaction)
  • Knowing what drug is best suited to your genotype will assist in finding the medicine that works, the first time
  • PGx testing will identify your metabolic status which in return will aid in choosing the correct dose, guesswork is eliminated

What happens after my test is completed?

Your PGx report will be sent to a designated email given at time of collection. In approximately one week, a certified Pharmacogenomics Pharmacist will be in touch to discuss your results.
