Histamine is one of the major mediators of allergic reactions. Thus, reasons to measure histamine in plasma or urine are often related to allergies. Some carcinoid tumors, particularly of gastric origin, produce and release excessive histamine. Urticaria pigmentosa, characterized by multiple, irregular, round or oval, yellowish brown to reddish brown macules and papules related to the presence of skin melanin overlying clusters of mast cells, can result in release of excessive histamine. Symptoms of flushing, itching, urticaria, vomiting, syncope, or shock are assumed to be due to histamine release, which coincides with increased urine or plasma levels. Systemic mastocytosis or basophilia can produce persistent elevations in plasma or urine histamine concentrations.
