Title: Blood urea nitrogen Authors: Venue: Wikipedia Year: unknown Canonical: wiki:blood-urea-nitrogen URL: https://en.wikipedia.org/wiki/Blood_urea_nitrogen Collector: wikipedia OA: true ABSTRACT Blood urea nitrogen (BUN) is a medical test that measures the amount of urea nitrogen found in blood. The liver produces urea in the urea cycle as a waste product of the digestion of protein. Normal human adult blood typically should contain 7 to 18 mg/dL of urea nitrogen. Laboratories may use slightly different reference ranges for BUN, depending on different assays. The BUN test is used to detect kidney problems. It is not considered as reliable as creatinine or BUN-to-creatinine ratio blood studies.
