A digital tool converts a prothrombin time (PT) result into an international normalized ratio (INR). This conversion standardizes PT results, which can vary based on the reagents and equipment used by different laboratories. For example, a patient’s PT might be 12 seconds, but their corresponding INR, calculated using the tool, might be 1.1.
Standardization through INR calculation is crucial for managing patients on anticoagulant therapy, such as warfarin. It allows healthcare professionals to accurately assess and adjust medication dosages, ensuring patient safety and preventing complications like thrombosis or bleeding. Historically, managing anticoagulation therapy was challenging due to the variability in PT results. The development and adoption of the INR system significantly improved the safety and effectiveness of these vital treatments.
