Urea
2NH4+CO3
**2-Coupled-
****Glutamate dehydrogenase/GLDH (coupled)
****-looks at the rate of dissappearance of NADH
***NH4+2-oxoglutarate-(GLDH)->Glutamate+H2O [NADH+H is oxidized]
===Sources of Lab Error:===
*Inhibition of urease – NH4, NaCitrate, NaFlouride
*Bact decomposition
*Hemolysis – minimal but preffered without
