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.
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.
Prothrombin Time (PT) 06-12895-03. Intended Use. The PT is a unitized coagulation test intended for in vitro use in performing a quantitative, one-stage prothrombin time. The PT test is performed using fresh canine, feline, or equine whole blood.

This online calculator is used to figure out the prothrombin time or INR ratio. PT patient (Seconds) PT normal (Seconds) ISI. International Normalized Ratio (INR) Calculation Definition, Formulae. The INR is a standardized prothrombin time designed to account for differences in thromboplastin.

The INR calculator is a tool that takes your PT and converts it into an INR value using the following formula: INR = (Patient’s PT / Mean Normal PT) ^ ISI. Where: Patient’s PT is the prothrombin time measured in seconds. Mean Normal PT is the average prothrombin time of a healthy population.
