Method and device for detecting hemolysis or for determining a correction factor which corrects the influence of hemolysis on a measurement of the hematocrit

摘要

A method of measuring hemolysis in whole blood, comprising the steps of irradiating the whole blood with radiation directed to the whole blood, detecting radiation incident from the first direction with respect to the incident radiation to perform a first measurement according to a first measurement method, and detecting a reference radiation incident on the incident radiation from a second direction for performing a second measurement according to a second measurement method, determining a first value for the hematocrit from the intensity of the radiation emerging from the first direction according to the first measurement method, determining a second value for the hematocrit the intensity of the radiation emerging from the second direction according to the second measuring method, the hemolysis being determined from the values for the hematocrit determined in the first measurement and in the second measurement, characterized in that the hemolysis is determined from the D If the first measurement is a reflection measurement (backward scattering) and the second measurement is a transmission measurement, the values determined for the first measurement and in the second measurement are determined for the hematocrit.
