Description

technical field [0001] The invention relates to the field of biological preparations, in particular to a urea detection kit, a preparation method and a use method thereof. Background technique [0002] Urea is the main end product of protein metabolism in the body. It has a small molecular weight and does not bind to plasma proteins. It can be freely filtered by the glomerulus. About 50% of the urea entering the primary urine is reabsorbed by the renal tubules and collecting ducts, and a small amount is excreted by the renal tubules. When the renal parenchyma is damaged, the glomerular filtration rate decreases and the blood urea concentration increases. The glomerular filtration function can be observed by measuring the blood urea or blood urea nitrogen concentration. [0003] At present, the determination methods of blood urea can be generally classified into enzymatic methods and chemical methods. enzymatic method. The amount of ammonium ions generated during the react...
