A single genetic variant can make the difference between effective cancer treatment and life-threatening toxicity. In this episode of LabMind, Ryan Nelson, PharmD, medical director of Precision Medicine at ARUP Laboratories and adjunct professor at the Spencer Fox Eccles School of Medicine at the University of Utah, shares how a growing movement led by patient advocates, researchers, healthcare organizations, and regulators has driven critical updates to guidelines for prescribing fluoropyrimidines, a major class of chemotherapy drugs. Tune in to learn why pharmacogenetic testing is becoming an important tool in cancer care, helping clinicians identify at-risk patients, reduce serious adverse events, and deliver safer, more cost-effective treatments.
