WebWhat is a high eosinophil count? A high eosinophil count is called eosinophilia and is classified by severity into three categories: Mild: 500–1,500 eosinophil cells per mL. Moderate: 1,500–5,000 eosinophil cells per mL. Severe: greater than 5,000 eosinophil cells per mL. Eosinophilia can occur due to any of the following: - Infection by ...
