Pharmacogenomic Test for Drugs Related to Psychiatric Disorders

This PGx test uses a simple cheek swab to test a combination of genes related to the metabolism of drugs used in the management of a wide range of psychiatric disorders.

If you are currently taking one of the following drugs, FDA recommends getting tested to determine if you have a gene mutation that could render a drug ineffective, cause unwanted side effects or result into a life-threatening event. Based on this information, your healthcare provider can suggest a different drug that can be safer and more effective.
