Scientific evidence indicates that pharmacogenetics, the study of drug interactions with an individual’s genetic makeup, may improve patient safety. Pharmacogenetic testing for some medications adds genetic information to the usual considerations of patient age, weight, disease process, use of other medications, health behaviors and environment. The additional information gained from pharmacogenetics can help prescribers choose and dose medication that best meets the needs of the individual patient.

Our Genetic Pharmacology Service (GPS) provides education about pharmacogenetics, clinical pharmacology and genetic testing.
