What are BUN-Creatinine Levels? BUN (blood urea nitrogen) is a blood test to check kidney function. So is the serum creatinine test. When your doctor talks about BUN/creatinine levels or a BUN-to-creatinine ratio, he or she is referring to the two main blood tests that tell how well the kidneys are filtering waste products from your blood. The ratio of BUN to creatinine is normally in the range of 10:1 to 20:1.

- Blood Urea Nitrogen. A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. 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.

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.

A person is advised not to consume a lot of meat or other protein-rich food 24 hours prior the test. A BUN test may be conducted together with a creatinine test.

What is blood urea nitrogen (BUN)? 384,845 Helpful Votes. A. Blood urea nitrogen (BUN) is a product of metabolism that is excreted in the urine. It is measured in the blood as an indirect measure of how well the kidney is functioning. Increased BUN levels in the blood may indicate early kidney damage, meaning the kidneys aren't effectively excreting BUN.
