A genetic test designed to help doctors determine the right drug and the right dose for a patient is being sold by The Mayo Clinic. It has been developed as part of the new field of pharmacogenetic testing. It offers tests for two genes that produce enzymes that break down drugs. These genes control how the body metabolizes 25 percent of all drugs.
Tests are available for some drugs used to treat Depression, Psychosis, ADHD, Heart Disease and Cancer, and Colon Cancer. (available from Roche's AmpliChip and Mayo Clinic Laboratories)
