Carglumic acid is an orphan drug used for the treatment of hyperammonaemia in patients with N-acetylglutamate synthase deficiency. This rare genetic disorder results in elevated blood levels of ammonia, which can eventually cross the blood-brain barrier and cause neurologic problems, cerebral edema, coma, and death.

N tau-methylhistamine is one of the histamine metabolites. N tau-methylhistamine in plasma and urine is a good parameter for histamine release and the determination of this histamine metabolite is generally less hampered by possible artifacts (due to basophil disrupture a very short half-life time or bacterial production) than determinations of histamine itself.
