Part Description

LP14492-0   Urea nitrogen
Urea nitrogen is the waste product formed in the liver when proteins are broken down into their respective amino acids. Once proteins are metabolized in the liver, urea nitrogen is released from the liver to the kidneys via the bloodstream. The kidneys then filter the urea nitrogen out of the bloodstream into the urine. Although the kidneys filter out most of the urea nitrogen in the blood, small traces of stable urea nitrogen remain in circulation. To evaluate kidney function, a blood urea nitrogen test (BUN test) is conducted. High amounts of urea nitrogen in the BUN test indicate complications with kidney function or decreased blood flow to the kidneys. A decrease in urea nitrogen in the BUN test is indicative of severe liver disease or malnutrition. [Lab Tests Online:bun/tab/sample/] Source: Regenstrief LOINC
