#354 How Pharmacogenomics is Revolutionizing Drug Prescriptions
DNA Today: A Genetics Podcast
Keeping PGx tests up to date
Kristy discusses allele updates, test lifecycle management, and sharing variant data via resources like ClinVar.
Why do some medications work perfectly for one person but cause side effects—or fail completely—for another? The answer often lies in our genes. Pharmacogenomic (PGx) testing analyzes how our DNA affects our response to medications, helping doctors personalize treatment, reduce adverse reactions, and improve outcomes.
Joining us today are Kristy Bouvier and Kathleen O’Brien from Quest Diagnostics, both of whom have decades of experience in the field. Kristy, a product manager, brings deep expertise in pharmaceuticals, while Kathleen, a board-certified genetic counselor, specializes in pharmacogenomics and hereditary oncology.
In this episode, we’ll explore:
✅ How pharmacogenomics (PGx) works and what results the test provides
✅ How PGx testing prevents adverse drug reactions and improves treatment
✅ Real-world examples of PGx in action
✅ Challenges and future trends in integrating pharmacogenomics into healthcare
✅ What patients should know before getting tested
