Urea is the end product of protein metabolism in the body. Urea is excreted by the kidneys through the urine. Part of the urea is eliminated through the gastrointestinal tract. Urea is synthesized in the liver and plays an important role in nitrogen metabolism. The main source of urea is from the body's protein degradation process.
Therefore, urine and blood urea quantification tests are often indicated to evaluate liver and kidney function and some other diseases. The higher the blood urea nitrogen, the worse the kidney function.
