What are Basophils?
Basophils are part of the body’s immune system – specifically white blood cells. During an inflammatory reaction, particularly a reaction caused by an allergen, basophils rush to the site and release heparin. Heparin prevents blood clotting. At the same time, the white blood cells release histamine to increased blood flow to the area. The body essentially thins the blood and increases blood flow to promote healing. The number of basophils in the blood is so low that low levels are extremely difficult, if not impossible to measure.
