Eosinophils are one of five types of WBCs found in the human body; all are produced by the bone marrow.

Eosinophils account for less than 7% of all circulating white blood cells and have two distinct functions: they destroy invading germs and create an inflammatory response, particularly if an allergy is involved. A healthcare professional may recommend an eosinophil count if you’ve already had a blood differential test and the results were abnormal. Specifically, an eosinophil count may be useful in the diagnoses of the following:
- An allergic reaction
- Infection by a parasite
- Cushing’s disease (a disorder caused by too much of the steroid hormone cortisol)
Normal reference range:
The normal reference range of Eosinophils is 1 to 7% of your total white blood cell count.
