What should be the amount of urea in the blood?
Protein taken through food is digested by the stomach and small intestine.
The protein that comes to the liver through the blood is broken down into ammonia, or in other words, waste material. This waste material, which is produced by the urea cycle that takes place in the liver, is converted into urea, making it less harmful. Urea, the end product of protein entering the human body through food, is released into the blood from the liver. This waste structure, which reaches the kidneys through the blood, is filtered by the kidneys and thrown out of the body through urine. However, if the kidneys cannot perform this function correctly, urea accumulation occurs in the body, which creates a toxic effect. Normally 100 ml. There should be less than 50 mg of urea in the blood. In laboratory tests, the normal urea value is between 10 and 40 mg/dL, and the BUN (Blood Urea Nitrogen) value is between 5 and 20 mg/dL. Urea below this value indicates that the needed protein cannot be digested by the body or that it is malnourished in terms of protein.
