Pharmacogenomics Testing
Overview
Pharmacogenomics (PGx) is the study of how genetic variations affect an individual’s response to medications. Our CLIA-certified laboratory uses advanced genotyping to evaluate multiple drug–gene interactions, identifying how a patient metabolizes, transports, or responds to specific drugs.
With PGx testing, providers can:
-
Optimize drug selection and dosing
-
Reduce adverse drug reactions
-
Improve treatment efficacy
-
Avoid trial-and-error prescribing
-
Support chronic disease management with precision medicine
