PGX stands for pharmacogenomics, which is the study of how a person’s genetic makeup can affect their response to medications. A PGX test is a genetic test that analyzes a person’s DNA to identify genetic variations that may affect their response to certain medications.
By identifying these genetic variations, doctors can tailor medication doses or choose different medications altogether to optimize their effectiveness and reduce the risk of side effects. PGX testing is particularly useful for medications with narrow therapeutic windows or high potential for adverse drug reactions, such as antidepressants, anticoagulants, and antiplatelet drugs.
It’s important to note that PGX testing is not always necessary or appropriate for everyone. Your doctor can help you determine if PGX testing is right for you based on your medical history, current medications, and other factors. Additionally, PGX testing is just one tool among many that doctors use to make treatment decisions, and it’s always important to discuss any medication changes with your healthcare provider.
