Genetic testing proves beneficial in prescribing effective blood thinners

A new research paper funded in part by the National Heart, Lung and Blood Institute (NHLBI) shows a clear advantage of genetic testing in helping health care providers choose the appropriate anti-platelet drug. Testing helps determine if a patient carries genetic variants in CYP2C19 that cause loss of its function. These variants interfere with the body’s ability to metabolize and activate clopidogrel, an anti-platelet medication.
