A new point-of-care test can rapidly identify people with a common genetic variant associated with impaired clopidogrel function. The authors claim that this is the first study to demonstrate the feasibility of delivering a genetic test at bedside. In an article published online in the Lancet, Jason Roberts and colleagues report on a new point-of-care test that can…
