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.

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
