This test measures the amount of histamine in the blood. Concentrations of histamine in the blood are normally very low. Significant increases can be seen in people having a severe allergic reaction and in those with a disorder in which the number of mast cells increase (proliferate) and/or activate without apparent allergies. Mast cells are large tissue mainly present in the skin, the lining of the intestine and air passages, and the bone marrow. Mast cells are part of the body’s normal response to injury as well as allergic (hypersensitivity) responses.
Signs and Symptoms of chronic hives include:
· Batches of welts (wheals) that can arise anywhere on the body
· Welts that might be red, purple or skin-colored, depending on your skin color
· Welts that vary in size, change shape, and appear and fade repeatedly
· Itchiness (pruritus), which can be intense
· Painful swelling (angioedema) around the eyes, cheeks or lips
· Flares triggered by heat, exercise or stress
· Symptoms that persist for more than six weeks and recur often and anytime, sometimes for months or years
Chronic hives don't put anyone at sudden risk of a serious allergic reaction (anaphylaxis). If you do get hives as part of a severe allergic reaction, emergency care is a must.
Please do not exercise prior to testing. It is best that your blood is taken in a rested state.
