Guide To The Types Of Leukocytosis

Eosinophilia

Eosinophilia is a type of leukocytosis marked by an elevated count of eosinophils in the blood. There are two variations of this condition, eosinophilia in the tissue and in the blood. Eosinophils are leukocytes that regulate inflammation and destroy foreign substances. They carry digestive enzymes that help break down foreign objects in the body such as parasites. When this condition is found in tissue, it is normally at the site of a localized injury or infection. When it is found in the blood, the elevated levels are often the result of an allergic reaction. 

This condition is also associated with certain lymphomas, so other tests will be done if the cause of elevated eosinophil levels is unclear. Because these cells are made to be destructive, an overabundance of them can cause damage to healthy tissue. If this is the case, corticosteroids are used to lower the level.
