What percentage of eosinophils normally constitutes white blood cells?

Eosinophils typically make up about 2-4% of the total white blood cells in a healthy individual. They play a crucial role in the immune system, especially in response to parasitic infections and in allergic reactions. Understanding there are various types of white blood cells, the specific percentage of eosinophils helps in assessing immune function and can be significant in differential diagnoses during a complete blood count (CBC). If the level of eosinophils is elevated, it may indicate allergies, infections, or other underlying conditions, while low levels could imply issues with the bone marrow production or other health problems.
