Accuracy, clinical correlation, and patient acceptance of two handheld prothrombin time monitoring devices in the ambulatory setting.
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. ⋯ The Coaguchek was superior to the ProTime Microcoagulation System in accuracy, clinical correlation, and ease of use. The study also showed that patients preferred capillary blood sampling by finger puncture over venipuncture for INR monitoring.
