PATHOLOGY

Detailed explanation-1: -In healthy individuals, eosinophils make up less than 5% of white blood cells. 1 An EOS count greater than this indicates an increased immune response and inflammation, which can point to issues ranging from allergies to certain cancers. Low levels can point to an issue with production of this cell type.

Detailed explanation-2: -Basophils have similar functions to mast cells and supplement their activity. They make up less than 1% of all leukocytes.

Detailed explanation-3: -Eosinophils usually account for less than 7% of the circulating leukocytes. A marked increase in non-blood tissue eosinophil count noticed upon histopathologic examination is diagnostic for tissue eosinophilia. Several causes are known, with the most common being some form of allergic reaction or parasitic infection.
