Title:
ENHACEMENT OF ACCURACY WHEN MEASURING HIGH-CREATININE-VALUE SPECIMEN
Document Type and Number:
WIPO Patent Application WO/2023/190087
Kind Code:
A1
Abstract:
Provided is a method which reduces measurement error that occurs when measuring a high-creatinine-value specimen. The present invention is a method for reducing measurement error that occurs in creatinine measurement of a biological sample suspected of having a creatinine concentration of not less than 120 mg/dL, said method being characterized by comprising (1) a step for mixing and reacting, with a biological sample, a first reagent that eliminates at least one substance selected from among the group consisting of creatine and sarcosine existing in the biological sample, and (2) a step for mixing and reacting, with the reaction liquid of step (1), a second reagent that measures creatinine existing in the biological sample, wherein the first reagent contains catalase, and the second reagent contains an azide.
