Abstract

In order to analyze a medical sample while avoiding error contributions due to hemolysis, prior to the main reaction for a component present in the sample, a pre-reaction is produced and measured by which the degree of hemolysis in the sample is determined and the result of the sample to be determined that is subsequently obtained is corrected by this error contribution using the relationship (correlation) that has been found between the degree of hemolysis and the error contribution.
