Abstract

The invention relates to a urine creatine quantitative test card, which comprises an upper shell, a lower shell, reaction test paper and developing test paper arranged in shell cavity, a pipette and a quantitative absorbing rod. The upper shell is provided with a sample loading hole; a solution tank is arranged in the shell; and the tail end of the reaction test paper is positioned in the solution tank. The urine creatine quantitative test card can realize instantaneous measurement of creatine in urine by combining simple and convenient urine quantitative dilution, enzyme reaction and chromatography developing technology, and has the advantages of simple structure, no need of mating instruments, convenient use, low cost, and accordance with application trend of point-of-care testing (POCT).

Description

technical field [0001] The invention relates to a urine detection card, in particular to a urine creatinine quantitative detection card for measuring creatinine concentration in urine. Background technique [0002] Creatinine is a product of muscle metabolism in the human body, and every 20g of muscle metabolism can produce 1mg of creatinine. In muscle, creatine is mainly slowly formed into creatinine through irreversible non-enzymatic dehydration reaction, and then released into the blood and excreted with urine. Creatinine is mainly filtered out of the body by the glomerulus (an important part of the kidney). Blood creatinine comes from both exogenous and endogenous sources. Exogenous creatinine is the product of meat food metabolism in the body; endogenous creatinine is the product of muscle tissue metabolism in the body. When the intake of meat food is stable and the body's muscle metabolism does not change significantly, the production of creatinine will be relatively...
