Pharmacogenomic Testing

Meaning

Pharmacogenomic testing is a sophisticated laboratory analysis that examines variations in an individual’s specific DNA sequence, particularly focusing on genes that encode drug-metabolizing enzymes and drug receptor targets, to predict their unique response to medications. This genetic insight allows clinicians to personalize drug selection and dosing regimens, moving from a generalized, trial-and-error approach to a more precise, genotype-guided therapeutic strategy. It represents a significant clinical tool for enhancing treatment efficacy, predicting therapeutic failure, and reducing the risk of serious adverse drug reactions.
