Pharmacogenomics studies the genetic makeup of patients to determine how they might respond to medications. These tests uncover whether patients are producing enzymes to effectively break down or use medication compounds and how well their bodies will excrete them. They also evaluate some genes which predict efficacy and/or side effects with certain medication classes. Using these results, providers can better determine which medications may work with clients. This will end the costly and exhausting trial-and error process for treating clients. This can be a welcomed relief for both providers and clients alike.
