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.

The activated partial thromboplastin time (aPTT or PTT) is an in vitro assessment of the intrinsic and common pathways of the classical waterfall-cascade model of coagulation. Although it does not reflect in vivo physiology depicted in the current revised model, the aPTT remains a practical and effective laboratory screening test1-4.

Rivaroxaban (XareltoR) is a direct anti-Xa treatment. It increases the aPTT and the Prothrombin Time (PT) in a dose dependent fashion. At a therapeutic dose, the P/C ratio is between 1.30 and 1.70, which is variable according to the reagent used. All the same, Dabigatran (Pradaxa®), a direct thrombin inhi-bitor increases the aPTT at ...
