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] Source: Regenstrief LOINC

Reference Information

Type Source Reference
Mapping Guidance Regenstrief Help Almost all laboratories name this "ammonia" but given the range of possible human pH, NH3 (ammonia) actually exists in the form of NH4+ (ammonium ion), and some labs might use the more precisea name. Most laboratories report this measurement in molar units [LOINC: 16362-6], but some do report it as a mass concentration. Plasma is the recommended specimen.
