A device designed for the self-monitoring of blood coagulation, commonly referred to as International Normalized Ratio (INR), allows individuals on anticoagulant therapy, such as warfarin, to manage their condition from their residence. These instruments provide a rapid, quantitative assessment of blood-clotting time, using a small blood sample, typically obtained from a finger prick. The obtained value assists patients and healthcare providers in determining the appropriate dosage of medication.
Regular monitoring of blood coagulation is critical for individuals prescribed anticoagulants to prevent both thromboembolic events and bleeding complications. Traditional laboratory testing requires frequent visits to healthcare facilities, leading to inconvenience and potential delays in adjusting medication. The capability to perform this testing at home offers significant advantages: improved patient convenience, greater control over therapeutic levels, and potentially, a reduction in adverse events associated with sub- or supra-therapeutic anticoagulation. This technology represents an evolution in patient-centered care, empowering individuals to actively participate in their healthcare management.
