ABSTRACT:
A method and apparatus is disclosed for measuring blood coagulation factor, operating on the principle wherein the clotting time (T) of a sample of blood to which a reagent has been added is measured; and then the measured clotting time (T) is converted into a quantity (A) in accordance with the equation: ##EQU1## where: Ao is an activation value amount taken on the assumption that an apparently negative or positive residual amount of coagulation factors, which are the object of measurement, exists in a diluted blood plasma solution prepared to obtain various values of activation, unit and concentration;
