Inside our body, proteins are catabolized to amino acids – the amino acids get deaminated. This process results in ammonia formation, which is synthesized in the liver as urea. This vital catabolic pathway is essential to remove large quantities of nitrogen from the body. This urea is an end product of protein and amino acid metabolism. The test measures the levels of urea in the blood.
