Gene Tests Could Predict if a Drug Will Work for a Patient.

Pharmacogenetic (PGx) tests can determine whether certain drugs will be effective for patients and what side effects to expect. These tests look for genetic differences that impact how individuals respond to medications. About 9 out of 10 people have genetic differences that affect their response to common medications. PGx testing is becoming more mainstream as test prices drop and insurance coverage expands. Research has shown that customized drug treatments based on PGx testing can lead to fewer side effects and better treatment outcomes for conditions such as cancer, heart disease, and mental health issues. However, the field is still considered emerging, and more research is needed. PGx tests are recommended before prescribing certain medications, such as antivirals for HIV and chemotherapy drugs. It is important to find a reputable testing provider and consult evidence-based resources for guidance on specific gene variants and drug interactions. The cost of PGx testing can vary, and insurance coverage may be limited. It is crucial to understand the results of the test and consult with a healthcare professional to interpret them correctly.
