OBJECTIVE To evaluate the accuracy, clinical correlation, ease of use, and patient acceptance of the Coaguchek and the ProTime Microcoagulation System as compared with standard laboratory methods for prothrombin time determination. METHODS A total of 30 prothrombin times, expressed as international normalized ratios (INRs), were determined by each handheld device for comparison with standard laboratory testing. Accuracy was evaluated by calculating the absolute difference for each pair of INR… CONTINUE READING
