摘要:
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;An is the normal or standard activation value of normal blood plasma;B is a constant used in converting from clotting time (T) into activation value;Tn is the clotting time of said normal blood; andP and Q are logarithmic bases;In order to eliminate the influence caused by Ao and minimize the errors deriving from the conversion.

A blood clotting end point detector which includes means for monitoring an electrical signal representing the value A of one or more optical properties of a blood plasma sample to which a coagulating agent has been added, means for deriving the first and the second differentials with respect to time of the value A, means for detecting the moment Ta when the second differential changes from negative to positive or becomes positive, means for detecting the moment Tb when the second differential next changes from positive to negative, means for deriving the difference (R) between the tangent to the curve A at the moment Ta and the curve A, means for determining whether the difference (R) or the integral, with respect to time from moment Ta to moment Tb, of the difference (R) exceeds a predetermined threshold value, in which case moment Tb is taken as the true clotting end point.
