PROBLEM TO BE SOLVED: To provide an immunoassay reagent capable of determining quantitatively, easily and precisely total hemoglobin in an urine sample mixed with erythrocytes, without requiring specific and special pretreatment.;SOLUTION: In this quantitative analytical reagent of the present invention, a surfactant for hemolyzing the erythrocytes mixed in an urine, and a polymer for promoting a particle aggregating reaction are added preliminarily in the reagent, in quantitative immunoassay for the total hemoglobin in the urine by a gold colloid particle flocculation method. Since the reagent is applicable for a versatile automatic analyzer, a treatment capacity is enhanced when treating a large amount of specimens as in a group examination, and labor saving and efficiency are expected to be enhanced.;COPYRIGHT: (C)2005,JPO&NCIPI
