Engelsk navn: | Urea Nitrogen | |
Analyseinstrument: | Advia®1800 | |
Reagensprodusent: | Siemens Medical Solutions Diagnostics | |
Analyseprinsipp: | Enzymatic: urease with GLDH The urea is hydrolysed in the presence of water and urease to produce ammonia and carbon dioxide. The ammonia reacts with 2-oxoglutarate in the presence of glutamate dehydrogenase and NADH. The oxidation of NADH to NAD is measured as an inverse rate reaction at 340 nm.
