Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

Your doctor may order an eosinophil count if the results of another blood test, called a blood differential, are abnormal. This test may also be done if the doctor thinks you may have a specific disease.

This test may help diagnose:

• Acute hypereosinophilic syndrome (a rare but sometimes fatal leukemia-like condition)
• An allergic reaction (can also reveal how severe the reaction is)
• Early stages of Cushing's disease
• Infection by a parasite
