What is the normal range for eosinophil count in the blood?

The normal range for eosinophil count in the blood is typically between 1-4%. Eosinophils are a type of white blood cell that play a crucial role in the body's immune response, particularly in fighting off parasitic infections and in allergic reactions. A percentage within this range indicates that the body has a normal level of eosinophils, which is important for maintaining a balanced immune system.

Counts below this range may suggest a potential deficiency or could indicate that the body is not responding adequately to infections or allergies, while counts exceeding this range can be a sign of various conditions such as allergies, asthma, autoimmune diseases, or parasitic infections. Therefore, understanding this normal range is vital for interpreting laboratory results and diagnosing potential health issues.
