The Absolute Eosinophil Count (AEC) test is a blood test that gives insights into your immune system's activity by measuring the level of eosinophils, a type of white blood cell. Eosinophils help the body fight off infections and are key in controlling inflammatory responses, especially those related to allergies. If your eosinophil levels are elevated, it can be a sign that your body is fighting an infection or reacting to allergens like dust, pollen, or certain foods.

Doctors often recommend the AEC test for individuals experiencing unexplained symptoms such as frequent allergic reactions, skin inflammation, or breathing difficulties, as well as for those with a history of asthma or autoimmune disorders. A high eosinophil count may indicate conditions like parasitic infections or immune disorders, while a normal count suggests that your immune system is functioning as expected. This test helps healthcare providers identify, manage, and treat conditions related to immune responses, ensuring timely intervention for better health outcomes.
