What is the purpose of this test?
The Eosinophil (EOS) Count Blood Test measures the number of eosinophils in your blood. Eosinophils are a type of white blood cell that plays a role in your immune system's response to allergic reactions, parasitic infections, and certain inflammatory conditions. An elevated eosinophil count may indicate an allergic condition, such as asthma or hay fever, or it could suggest the presence of a parasitic infection.
During the test, a blood sample is taken from your arm and analyzed in a lab to count the number of eosinophils present. This test helps doctors diagnose and monitor conditions where eosinophil levels are important indicators, such as allergies, asthma exacerbations, or parasitic infections. Understanding your eosinophil count helps healthcare providers determine the appropriate treatment and management plan for your specific condition.
