Therapeutics testing covers a wide range of areas from controlled substance monitoring to pharmacogenomics (PGx). Our testing delivers clarity on drug use to advance understanding and improve patient outcomes. We provide access to Mayo Clinic experts and a test menu developed through evidence-driven clinical innovation to help clinicians guide patient care.
“The goal is not to identify every drug technically possible, but to perform medically necessary testing for those drugs that are most likely to impact clinical outcomes.”
