Urea (urine) | Laboratory research

General Information

Urea Is the end product of protein metabolism in the body. The major site of urea production is the liver, however, tissue during growth (e.g., embryonic tissue or tumor tissue) tends to produce urea from arginine.

Most of the urea is excreted by glomerular filtration; 40-60% is reabsorbed into the blood, depending on the rate of flow in the tubules and the concentration of antidiuretic hormone (ADH).

Urea excretion depends on diet; It increases in the case of a protein-based diet and decreases in the case of a vegetarian diet.
