Pharmacogenetic Tests

Pharmacogenetic Tests are used to find how genes affect the body’s response to certain medicines. You may submit a blood sample or a saliva sample to get tested. For a saliva test, you should not eat, drink, or smoke for 30 minutes before the test.


Below are some of the medicines and genes that can be tested in Pharmacogenetic Tests:

Medicines Genes
Warfarin CYP2C9 and VKORC1
