Coagulation assay for the quantitative determination of Prothrombin Time (PT) in human citrated plasma. The lyophilised reagent is sensitive to abnormal levels of coagulation factors II, VII and X and is used for the monitoring of oral anticoagulant therapy (i.e. warfa-rin). The reagent contains rabbit brain thromboplastin and adsorbed bovine plasma as a source for the coagulation factors V and fibrin-ogen. Technoclot® PT Owren replaces Thrombotest und Normotest.

Test principle

The reagent is added to the prediluted plasma sample and incubated for 3 min at 37°C. Start timing of the coagulation with the addi-tion of CaCl2.
