Abstract:
We evaluated a new portable device (CoaguCheck XS) for measuring the prothrombin time-international normalized ratio (PT-INR) in 63 patients after cardiac surgery, and compared the results with those of the conventional method. There was a good correlation between the PT-INR values measured conventionally and those obtained with the CoaguCheck XS. This new device was easy to use, data were obtained rapidly, and the results were reliable. The CoaguCheck XS will be particularly useful for outpatients. PT-INR self-management is expected to be introduced as soon as health insurance coverage is obtained.
