Urea is measured as part of the U&E profile to evaluate renal function. It can be used in conjunction with creatinine for the differential diagnosis of pre-renal, renal and post-renal uraemia.
|Tube||01 (SE) - Serum Gel|
|Additional Information||Urea is the final degradation product of proteins and amino acid metabolism. In protein catabolism, the proteins are broken down to amino acids and deaminated. The ammonia formed in this process is converted to urea in the liver. This is the most important catabolic pathway for eliminating excess nitrogen in the body.|
