Pharmacogenomic (PGx) testing may be recommended when a more personalized approach to psychiatric medication management could improve treatment decisions. Because every person processes medications differently, genetics can influence how well certain medications work and the likelihood of experiencing side effects. PGx testing provides additional information that helps healthcare providers individualize treatment based on your unique genetic profile.

Your provider may consider PGx testing if you have experienced multiple medication trials with limited improvement, troublesome side effects, or difficulty finding the right medication or dose. It may also be helpful if you take several medications, have a family history of medication sensitivities, or are starting medications for conditions such as depression, anxiety, ADHD, bipolar disorder, PTSD, or other mental health disorders.

While pharmacogenomic testing is not appropriate for every patient and does not replace a comprehensive psychiatric evaluation, it can provide valuable insights that support evidence-based prescribing. When combined with your medical history, current symptoms, lifestyle, and treatment goals, PGx testing helps your provider make more informed medication decisions that may reduce unnecessary medication changes, improve tolerability, and support better long-term mental health outcomes through personalized care.
