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.
