Pharmacogenomics-Supported Psychotropic Prescribing Trial

This study tests whether using genetic testing (pharmacogenomics) to guide which psychiatric medications a doctor prescribes leads to better outcomes for patients. A saliva sample is used to identify genetic variations that affect how a person processes certain medications. **You may be eligible if...** - You are 18 years or older - Your doctor has decided you need to start, change, or adjust a psychiatric medication (such as an antidepressant or antipsychotic) - Your treating doctor believes genetic testing would help guide your prescription **You may NOT be eligible if...** - You refuse to provide a saliva sample for genetic testing - You have had a liver or bone marrow transplant - You already have pharmacogenomics (genetic drug response) test results available - You do not have a personal health identification number Talk to your doctor to see if this trial is right for you.
