I some Marfan syndrome - Affected know almost all of which have to control your blood clotting by various operations by medication, is this post about the difference between the Quick and the INR value. Because of the Scope of the topic describes, this post short and sweet this difference. At the end of this article is an external link that shows the details very well the difference. The Quick value was described as a medical laboratory parameters from the U.S. physician Armand James Quick for the first time. It is a measure of operational performance of the extrinsic system (from outside) of blood coagulation. It stands in contrast to the partial thromboplastin time (PTT), the information on the functional performance of the intrinsic system (from within) are.
International Normalized Ratio (INR) is the result of standardization for prothrombin time. International indicates blood clotting time on the basis of this reading. This standardization was necessary because of the Quick value provides an identical, accurate measurement due to charge-dependent differences in activity of the prothrombinase partially different results.
As a practical example of why the INR value and not the Quick value is to be determined is on a vacation trip. If it is necessary that we determine in a practice of the resort of the coagulation value of INR value should be identical to a measurement in a practice where you live. In the Quick value of this comparison between the two places would be partially different.

own experiences, I must explain that in some medical practices are still not self-evident that in clotting determination of INR value is determined, but rather the Quick value. Therefore, one should always exist as a concerned party on the INR value is determined (even if it caused some discussions).
