Use to assess genetic risk of abnormal drug metabolism for drugs metabolized by CYP2B6, CYP2C19, CYP2C8,CYP2C9, CYP2D6, CYP3A4, and CYP3A5. May aid in drug selection and dose planning for many drugs. This test includes access to the GeneDose database; for testing that excludes GeneDose access, refer to Cytochrome P450 Genotyping Panel (3001524).
