Part Descriptions

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

LP7238-1   Body fld
The LOINC "Body fld" System represents body fluids other than serum, plasma, blood, urine, and cerebrospinal fluid. When a LOINC term with the System "Body fld" is used, the specific specimen source or body fluid type should be reported elsewhere with the result. Where more specific terms for pleural, peritoneal, synovial fluid, etc. exist, we encourage you to use the more specific terms. In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" is used for abnormal fluid collections that are aspirated, while "Body fld" is used for named body fluids, such as synovial fluid or peritoneal fluid, that are not inherently pathologic.
