For teaching strategies to be included on this list, they had to: 1  Be supported by hard research, instead of anecdotal case studies or untested theories. 2  Have a substantially higher effect on student results than other teaching strategies. 3  Be able to be used on a wide range of subjects and in every year level.
Prothrombin. Prothrombin is a blood-clotting protein. Injury to a blood vessel produces a signal which triggers the conversion of prothrombin to thrombin. Thrombin is a protein which plays a central role in provoking the assembly of other proteins to form the blood clot.rothrombin consumption test a test to measure the formation of intrinsic thromboplastin by determining the residual serum prothrombin after blood clotting is complete.
The prothrombin time is the time it takes plasma to clot after addition of tissue factor (obtained from animals such as rabbits, or recombinant tissue factor, or from brains of autopsy patients). This measures the quality of the extrinsic pathway (as well as the common pathway) of coagulation.
