Eosinophils are a specialized type of white blood cell (granulocyte) primarily responsible for combating multicellular parasites and certain infections. They play a major role in the mediation of allergic reactions and asthma. In a Complete Blood Picture (CBP), the absolute count (rather than the percentage) provides the most accurate assessment of eosinophilia. They contain granules filled with cytotoxic proteins that are released to destroy pathogens, but this can also cause tissue damage in chronic inflammatory states.

Why Context Matters
Eosinophil counts fluctuate throughout the day (diurnal variation), being lowest in the morning. Corticosteroid use significantly suppresses eosinophil counts, which may mask an underlying condition.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
