Clinical Utility

Histamine is one of the major mediators of allergic reactions. Histamine levels may be increased in some carcinoid tumors (particularly of gastric origin), urticaria pigmentosa, and with symptoms of flushing, itching, uticaria, vomiting, syncope, or shock. Increased histamine levels are also associated with allergies, systemic mastocytosis or basophilia.
