Hemostasis/coagulation assays: Prothrombin time (PT)
Hemostasis/coagulation assays: Prothrombin time (PT)
This is one of threecoagulation/hemostatis assaysto measure clotting and is an automated plasma analysis, supporting translational research studies.
The Prothrombin time (PT) assay uses an extrinsic pathway to measure the speed of clotting, including factors for VII, X, V and II.

About the International Normalized Ratio (INR)
国际标准化比率(INR)是一个斯坦dardized equation of measuring (coagulation) time in a blood sample in order to unify the results of prothrombin time (PT) acquired from different laboratories, using different reagents.
By comparing PT tests with a control value (mean value in health) and applying a correction factor specific to the equipment (international sensitivity index, ISI), a standardized value is produced: INR = [PT(test)/PT(control)] ISI.
About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC.Learn more about our commitment to replacing, reusing and refining nonclinical research models.
