patients monitor their own warfarin therapy AT HOME
There's growing interest in having patients monitor their own warfarin therapy AT HOME.
Some companies are now testing portable prothrombin (PT) analyzers (Coumatrack, etc).
When these get approved, patients will use a drop of blood from a fingerstick...much like diabetics perform blood sugar testing. Patients will get instructions on how to adjust their warfarin dose based on the test results.
