1. Method for immunologically determining glycated hemoglobin in blood, comprising:
- (a) treating a blood sample which contains said glycated hemoglobin with a hemolysis reagent consisting essentially of an ionic detergent which has a pH of from 5.5 to 9.5, for a period of no more than 10 minutes, at a temperature of from 4°
C. to 37°
C., to hemolyze said blood sample,(b) contacting the hemolyzed blood sample with at least one immune reagent which specifically binds to glycated hemoglobin, and(c) determining binding of said immune reagent as a determination of glycated hemoglobin in said blood sample.

Abstract
The invention concerns a method for the determination of the content of a particular haemoglobin derivative in a blood sample. In particular, the invention concerns a method for the determination of the content of haemoglobin derivatives such as glycated haemoglobin which require the separate determination of the total haemoglobin content and the determination of the haemoglobin derivative in order to determine the proportion of the derivatized haemoglobin in the blood as well as a suitable haemolysis reagent for this.
