About Histamine (blood)

What is histamine?

Histamines are produced by the body’s immune system often in response to an allergen. They are made by mast cells which are found in the skin, the lining of the lungs, intestines and air passages. The release of histamine causes local swelling, redness and itching. Low levels of histamine are found in the blood of healthy people.

However, the levels may increase in severe allergic reactions or in mastocytosis. Mastocytosis is a condition in which too many mast cells are made. The mast cells then accumulate in the skin (cutaneous mastocytosis) or internal organs (systemic mastocytosis).

Why take the test?

This test measures the level of histamine in the blood and can be used to help diagnose a severe allergic reaction or mastocytosis.
