What is the normal range for eosinophils in the blood?

• A. 0-1%
• B. 1-4%
• C. 2-8%
• D. 55-75%

Answer: (B)

Eosinophils are a type of white blood cell that play a vital role in the body's immune response, particularly in combating parasitic infections and mediating allergic reactions. The normal range for eosinophils in the blood is indeed 1-4% of the total white blood cell count. This range indicates a typical physiological level; when eosinophil counts exceed this range, it could suggest conditions such as asthma, allergies, or parasitic infections. Conversely, if levels drop below this range, it may indicate issues related to immune function. Understanding the normal range helps healthcare providers identify potential abnormalities in immune responses or infections, aiding in making accurate diagnoses and treatment plans.
