Warfarin Sensitivity DNA Test Launches

Posted Nov 19 2009 10:02pm

Have you had a blood clot or DVT? If so, chances are you’ve been on warfarin (brand name: Coumadin). Warfarin, a blood-thinner, is the most commonly prescribed drug for preventing and treating blood clots.

Warfarin is also known to be a difficult drug to manage, for two reasons. First, the blood levels in which warfarin is effective are very narrow, which means doctors need to carefully calibrate the dose. Secondly, people have a wide range of responses to it, which means calibrating the dose is more challenging.

Kimball Genetics (a laboratory) has just launched a genetic test for warfarin sensitivity, which better predicts an individual’s response to warfarin. This test can help your doctor determine the warfarin dosage that’s best for you — lowered risks, maximum effectiveness.

The test looks for variations in two genes, CYP2C6 and VKORC1. The first gene, CYP2C9 plays a role in how your metabolize drugs. The second gene is involved in anticoagulation process. You can read more about how genes affect drug metabolism on my company’s website.
