Hi – I am a genetic counselor, and I wanted to share some important information about drugs and genetics. The FDA has begun including gene-and-drug-response information in drug labels, so that healthcare providers and patients have updated information on how genetics, along with other factors (age, gender, liver and kidney function, other medications) can influence a person’s response to a particular drug. One drug with this labeling is warfarin (also called Coumadin).
There is a test to determine how you respond to warfarin that gives important information about the dose you need to take. This test looks at 2 genes involved with breaking down warfarin in the body, called CYP2C9 and VKORC1.
DNA Direct has detailed information on our website (www.dnadirect.com) for you to learn more. This testing is useful for people who are taking or considering taking warfarin.
You can order the testing on your own directly from the website or your physician can complete the online referral form. Testing is simple and painless. Please contact clinical services 877-646-0222 or email@example.com to talk with a genetic expert.
Because this is a new type of testing, we are inviting a limited number of people to have this testing done at no charge. In return, we ask for feedback about your testing experience. Please contact me at firstname.lastname@example.org for more information about this free testing.
