Method – GLDH-Kinetic
Pack Size : R1: 4 x 100 ml R2:2x50ml
Principle
Urea is hydrolyzed to ammonia and carbon dioxide by urease. Ammonia produced reacts with @-ketoglutarate to form glutamate in presence of glutamate dehydrogenase. NADH is oxidized to NAD* in this reaction, which Is measured as a decrease in absorbance at 340 nm. The rate of decrease in absorbance at 340 nm. is directly proportional to BUN concentration in the specimen. The BUN concentration in the specimen is determined by comparing the sample reaction rafe to that obtained with a BUN standard
