As the liver metabolizes food, it decomposes and produces amino acidsNitrogen> as part of the waste product urea. When the kidneys are functioning properly travels urea by the liver to the kidneys for excretion in the urine. However, if the kidneys are not working properly, do not remove urea from the most effective, increasing levels of blood urea nitrogen.

A BUN test measures the amount of urea nitrogen in the blood to diagnose if you have a kidneyproblem. This test is often done with a creatinine test the blood for an accurate diagnosis. Determines the BUN-to-creatinine, which may help reveal whether there are other problems such as dehydration affects the results.

However, a higher than normal result does not necessarily indicate a kidney disease. The results of the urea may be elevated due to dehydration, heart failure, trauma, internal bleeding, bad food.
