Coagu-Sense Performing a PT/INR Test
3 Αυγ 2015 · Normal PT in cats is less than 22 seconds, but this can vary from laboratory to laboratory. Values greater than 22 seconds indicate a potential bleeding disorder. The most common cause of a prolonged prothrombin time is poisoning with an anticoagulant rodenticide.
8 Ιουν 2024 · INR is a standardized measure of PT, ensuring consistency in results across different laboratories. The normal range for INR is around 0.8 to 1.2. Higher INR values suggest a slower clotting time and an increased risk of bleeding.
Substances important include antithrombin (AT) which, in association with heparin, inactivates many of the coagulation factors, and prostacyclin (PGI2), produced by blood vessel endothelial cells, which inhibits platelet aggregation and causes vasodilation.
