Portable prothrombin time and international normalized ratio (INR) monitoring devices allow individuals requiring regular INR checks, such as those on anticoagulant therapy (e.g., warfarin), to conveniently self-test at home. These handheld devices typically utilize a small blood sample obtained through a finger prick and provide results within minutes. This accessibility empowers patients to actively participate in managing their health, leading to improved anticoagulation control.
Regular monitoring of prothrombin time/INR is crucial for patients on anticoagulants to ensure the medication’s effectiveness and minimize the risk of complications like bleeding or clotting. Home testing provides greater flexibility and reduces the need for frequent clinic visits, improving patient adherence and quality of life. Historically, INR monitoring required laboratory testing, which could be time-consuming and inconvenient. The advent of portable devices has revolutionized anticoagulation management, enabling more proactive and patient-centered care.
