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.
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.
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 test is to be used with the Coag Dx* Analyzer and is also compatible with the SCA2000* Coagulation Analyzer.

3 Αυγ 2015 · Without treatment, bleeding disorders can sometimes cause the death of affected animals, including cats. One of the tests used to help determine a possible cause of a bleeding disorder is the prothrombin time (PT). Checking PT is indicated in any pet with a suspected coagulation problem.
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.
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.
