Cause of High Eosinophil Count
An increase in the number of eosinophil, a type of white blood cell, is commonly associated with an allergy or infection. Eosinophil count can be seen in a routine complete blood count.

High eosinophil count can signify a number of reasons:
- infection caused by parasitic worm (such as ascaris and hookworm)
- allergy
- asthma
- allergic rhinitis
- atopic dermatitis
- automimmune disease
- hay fever
- drug allergy
- eczema
- cancer
- fungal infection
- cushing syndrome
- lymphoma
- leukemia
- lupus
- organ transplant rejection
- adrenal insufficiency
- addison's disease
- mastocytosis
Eosinophilia is a condition in which eosinophil count is more than 500 µl.
Hypereosinophilic syndromes (HES) is a rare condition in which eosinophil count is high (more than 1500/µl) and persists for 6 months or more. It is associated with damage to organ.
Eosinophil composes about 1-3% of white blood cells. Eosinophils are produced in the bone marrow which later migrates to tissues where they can last for 8 to 12 days.
