Part Descriptions

LP14288-2   Urea
A compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids. Source: National Library of Medicine, MeSH 2006

LP14288-2   Urea
Urea, also called carbamide, is an organic chemical compound involved in the metabolism of nitrogen-containing compounds and in the re-absorption of water and critical ions from excreted urine, an important mechanism in prevention of water loss and maintaining blood pressure. Urea levels are measured to diagnose conditions that affect the kidneys, such as acute kidney failure or end-stage renal disease (ESRD). The blood urea nitrogen (BUN) and the urine urea nitrogen (UUN) tests may be used to determine how well a patient's kidneys are functioning. Increased or decreased levels of urea may also suggest dehydration or increased protein intake. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

Mapping Guidance LOINC This term was made to accommodate a laboratory system outside of the US. LOINC currently discourages the use of specimens combining ser/plas and blood in one term (as ser/plas/bld) for two reasons. First, practices usually want to distinguish the two on ordering since whole blood usually implies a point of care test and ser/plas usually implies sending to another location. Second, whole blood tests are usually classified as low complexity (waived) under CLIA regulations, and because waived tests are excluded from the annual COLA report of testing volume (required by the Centers for Medicare and Medicaid Services) and ser/plas tests are not, the two have to be distinguished.
