Ammoniemia
Definition
The presence and concentration of ammonia or ammonium ions in the circulating blood. Normally, its level is kept very low through its rapid conversion into urea in the liver; the quantitative determination of amoniemie is crucial for diagnosing severe hepatic insufficiency, advanced cirrhosis, or inborn errors of metabolism within the urea cycle.
