DescriptionUrea 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 synthesised to urea in the liver. This is the most important catabolic pathway for eliminating excess nitrogen in the body.
IndicationUsed to evaluate renal function. Test is frequently requested in conjunction with creatinine for the differential diagnosis of prerenal, renal and postrenal uraemia.
