Using the latest discoveries in PGx, the Xfinity lab Drug Sensitivity Genetic Test profiles and analyzes your unique genetic characteristics in terms of drug effectiveness and safety. Knowledge of your genetic information can guide you and your physicians to make more precise, personalized and safer medical choices.
