Problems solved by technology

Song Jingfang, Pan Benyou, Wu Xianding et al. (Clinical research on the effect of calcium dobesilate on the detection of serum creatinine by oxidase method [J]. Contemporary Medicine, 2019,25(09):175-177) studied the effect of calcium dobesilate on creatinine In the case of interference in the enzyme method, it was found that calcium dobesilate would cause a negative deviation in the creatinine assay kit (sarcosine oxidase method)

Abstract

The embodiment of the invention discloses a human serum creatinine content detecting reagent for resisting calcium dobesilate interference. The detection reagent comprises a first reagent, a second reagent and a third reagent, wherein the first reagent comprises sodium carbonate. The detection reagent is used for determining human serum creatinine based on an enzyme method, and besides, interference of calcium dobesilate drugs in serum can be avoided. The defect for detecting creatinine by a conventional enzyme method is overcome. The embodiment of the invention further provides a human serumcreatinine content detecting method for resisting calcium dobesilate interference.

Description

technical field [0001] The invention relates to the technical field of human body biochemical detection, in particular to a human serum creatinine content detection reagent and method which are resistant to calcium dobesilate interference. Background technique [0002] Creatinine is the final metabolite of creatine produced within muscle cells. In kidney disease and muscle disease with low renal function, the serum creatinine concentration increases; in muscular dystrophy, the serum creatinine concentration decreases. The excretion of creatinine in urine is directly proportional to the total amount of muscle, and is not affected by food, urine volume, and renal tubular reabsorption, so it can be used for the examination of glomerular filtration function. [0003] In the past, the basic picric acid method (Jaffe method) was often used to measure creatinine. This method belongs to the traditional creatinine detection method, but its disadvantages are low specificity, more int...
