A portable device used for analyzing blood coagulation, particularly the prothrombin time (PT) and international normalized ratio (INR), assists healthcare professionals in monitoring patients receiving anticoagulant therapy, such as warfarin. This device allows for point-of-care testing, often providing results within minutes. A typical example uses a small blood sample, often obtained through a finger prick, applied to a test strip inserted into the device. The device then analyzes the sample and displays the PT and INR values.
Rapid and convenient coagulation assessment is crucial for managing patients on anticoagulation therapy. Regular monitoring helps ensure the dosage is appropriate, minimizing risks of bleeding complications or thromboembolic events. This portability enables testing in various settings, including hospitals, clinics, and even patients’ homes, increasing access to timely results and improving patient compliance with treatment. The development of these portable devices has significantly improved anticoagulation management compared to traditional laboratory testing, which often involves longer wait times for results.
