What is a normal eosinophil count?
A normal eosinophil count is generally no higher than 350 eosinophils per microL of whole blood. 5) What is a high eosinophil count? An eosinophil count over 400-450 per microL of whole blood is considered high. In severe forms of eosinophilia, the number of eosinophils can be as high as 5,000 cells. 6) What causes eosinophilia? The exact causative mechanisms of eosinophilia remain largely unclear. Many cases of eosinophilia are termed “idiopathic”, which means “of unknown origin”.
