BUN-to-creatinine ratio The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion.

Blood Urea Nitrogen (BUN) Test A blood urea nitrogen (BUN) test is used to determine how well your kidneys are working. It does this by measuring the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that’s created in the liver when the body breaks down proteins. Normally, the kidneys filter out this waste, and urinating removes it from the body. BUN levels tend to increase when the kidneys or liver are damaged.

Urea is made in the liver and passed out of your body in the urine.A BUN test is done to see how well your kidneys are working.If your kidneys are not able to remove urea from the blood normally, your BUN level rises.Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. Liver disease or damage can lower your BUN level.f your kidneys are not able to remove urea from the blood normally, your BUN level rises.

Understanding Your Lab Values Blood Urea Nitrogen (BUN): Urea nitrogen is a normal waste product in your blood that comes from the breakdown of protein from the foods you eat and from your body metabolism. It is normally removed from your blood by your kidneys, but when kidney function slows down, the BUN level rises. BUN can also rise if you eat more protein, and it can fall if you eat less protein. Urine Protein: When your kidneys are damaged, protein leaks into your urine. A simple test can be done to detect protein in your urine. Persistent protein in the urine is an early sign of chronic kidney disease.

Blood Urea Nitrogen A blood urea nitrogen (BUN) test measures the amount of urea nitrogen found in your blood. BUN levels help your doctor see how well your kidneys are working. The test may be used along with other measurements to help diagnose a kidney disorder or find out how well your treatment for kidney disease is working.our doctor may also check the creatinine levels in your blood. On its own, the BUN level does little to tell your doctor about your kidney, or renal, function. But when it is measured along with creatinine levels, your doctor can look at how these two levels compare to help find out your kidney function.

Blood urea nitrogen Blood urea nitrogen. The liver produces urea in the urea cycle as a waste product of the digestion of protein. Normal human adult blood should contain between 6 and 20 mg of urea nitrogen per 100 ml (6–20 mg/dL) of blood. Individual laboratories will have different reference ranges as the assay used will vary between laboratories.

Overview Urea nitrogen levels tend to increase with age. Infants have lower levels than other people do, and the range in children varies. Generally, a high blood urea nitrogen level means your kidneys aren't working well. But elevated blood urea nitrogen can also be due to: Urinary tract obstruction. Congestive heart failure or recent heart attack. Gastrointestinal bleeding. Dehydration, resulting from not drinking enough fluids or for other reasons.
