Arkray offers coagulation reagents, including reagents for Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) tests. These reagents are used in conjunction with the Arkray Thrombostat, an automated coagulation analyzer, for in-vitro diagnostic blood coagulation analysis. The analyzer is designed for both laboratory and mobile use and is capable of determining PT, a PTT, and Thrombin Time (TT) parameters.
