Abstract
(EN)
Provided are a method of measuring hematocrit value whereby a hematocrit value can be measured at a high accuracy, and a system for measuring hematocrit value. A method of measuring the hematocrit value of a blood specimen by a coloration reaction with the use of a color development reagent reacting with a component in the blood differing from hemoglobin, characterized in that the hematocrit value of the blood specimen is calculated based on an optical characteristic (a1) of the blood specimen measured with a light (λ1) having at least one absorption peak wavelength that is specific to hemoglobin and another optical characteristic (a2) of the blood specimen measured with a light (λ2) having at least one absorption peak wavelength that is specific to a colorant formed by the coloration reaction as described above.

L'invention porte sur un procédé de mesure d'une valeur d'hématocrite, par lequel une valeur d'hématocrite peut être mesurée avec une précision élevée, et sur un système pour mesurer une valeur d'hématocrite. L'invention porte sur un procédé de mesure de la valeur d'hématocrite d'un échantillon par une réaction de coloration avec l'utilisation d'un réactif de développement de couleur réagissant avec un composant dans le sang différent de l'hémoglobine, caractérisé par le fait que la valeur d'hématocrite de l'échantillon sanguin est calculée sur la base d'une caractéristique optique (a1) de l'échantillon sanguin mesurée avec une lumière (λ1) ayant au moins une longueur d'onde de pic d'absorption qui est spécifique à l'hémoglobine et une autre caractéristique optique (a2) de l'échantillon sanguin mesurée avec une lumière (λ2) ayant au moins une longueur d'onde de pic d'absorption qui est spécifique à un colorant formé par la réaction de coloration comme décrit ci-dessus.
