The International Normalized Ratio (INR) calculator is a simple, free tool to assess the unified prothrombin time (PT), and its meaning. It's an easy way to evaluate both the extrinsic pathway and the common pathway of coagulation.
Prothrombin time (PT) measures the functional activity of the coagulation factors involved in the extrinsic and common pathways. These parameters are measured by the amount of time it takes for a fibrin clot to form after calcium and different activating factors are added to a blood sample.
Clotting times >30% prolonged compared to controls are considered abnormal. Individual clotting factors need to be <30% before APTT or PT are prolonged. Point of care coagulation instruments (e.g., SCA2000) can determine the APTT and PT on small amounts of fresh citrated whole blood. These have been shown to be reliable in dogs.
