# Eosinophil Count

> This test measures the level of eosinophils, a type of white blood cell that becomes active during allergic reactions and parasitic infections. It helps show whether your immune system is responding to triggers like allergens, asthma, or certain parasites. Doctors use this information to help distinguish between different types of immune responses or inflammatory conditions. However, this count alone cannot identify the specific allergy or infection responsible for the result.
