PT/PTT are laboratory tests that measure the clotting time (how long it takes blood to clot.). PT/PTT are blood tests and INR is a ratio calculated from the PT. At least a dozen blood proteins, or blood clotting factors, are needed to clot blood and stop bleeding (coagulation).Prothrombin, or factor II, is one of several clotting factors produced by the liver.OW PT/PTT = risk for blood clots/ stroke. The INR stands for International Normalized Ratio. The INR is calculated from the PT and is intended to allow valid comparisons of results regardless of the type of PT reagent used among different laboratories (INR = [patient PT / mean normal PT]).
