Part Description

LP14071-2   Ammonia
Ammonia (NH3) is produced in the body as a byproduct of the metabolism of amino acids and other compounds, is processed in the liver to form urea which is ultimately eliminated in the urine. Elevated blood concentrations of ammonia are toxic and can lead to brain damage, coma and death. [PMID:31082083] Testing of ammonia levels is most commonly performed to monitor various diseases and less so for occupational exposure or poisoning. Conditions associated with elevated ammonia include severe liver disease, Reye syndrome, kidney failure, and certain rare genetic diseases. Ammonia levels may also be measured to evaluate the effectiveness of treatment of hepatic encephalopathy.[Lab Tests Online:Ammonia] Copyright Copyright ©2005-2009 Genome Alberta (Reference to original publication: Wishart DS, Knox C, Guo AC, et al.
