Eosinophils or acidophils are bone marrow derived cells of granulocyte lineage, responsible for combating multicellular parasites and certain infection in vertebrates. This is a type of white blood cell that contain granules that are readily stained by eosin dye.
In normal individuals, eosinophils make up about 1-3% of white blood cells and are about 12-17 micrometers in size with bilobed nuclei. The normal eosinophil count is less than 500 per microliter of blood. A change in eosinophil count is an indicator of any allergic condition or infection inside the body.
In normal conditions, eosinophil count is low in morning and increases by evening. Children also have high eosinophil count in general.
In this article, we will share in detail about eosinophil and various conditions associated with it
