Eosinophils (B-Eos)

Eosinophils is part of the Complete blood count. The number of white blood cells (Leuk) is the actual number of white blood cells in proportion to the blood volume. Either a decrease or an increase may be significant. There are five types of white blood cells, which carry out separate tasks in protecting the body against infection: neutrophils (Neut), lymphocytes (Lymf), monocytes (Mono), eosinophils (Eos), and basophils (Baso).

Eosinophils are white blood cells in the immunological defence system, participating in nearly all vital functions. They are also called granulocytes and their numbers respond to allergies and parasitic infections.
