Clinical Utility and Accuracy of Coaguchek(R) XS, a Reliable Alternative to Laboratory International Normalized Ratio Monitoring in Korean Patients With Atrial Fibrillation
To evaluate the accuracy and the clinical utility of the Coaguchek(R) XS, a portable point-of-care coagulometer, compared to standard laboratorymethods in Korean patients. SUBJECTS AND
The INR determined by the portable Coaguchek(R) XS had excellent correlation with the values obtained by standard methods (r=0.984, p3.0). There was a 91.6% agreement between the two methods. Only nine cases (8.4%) had a difference of more than 0.3; this was mainly noted in the high INR group.
