About this test
The Absolute Eosinophil Count (AEC) is a blood test that quantitatively measures the number of eosinophils, a type of white blood cell, in a given volume of blood. This test is primarily used to investigate and monitor conditions such as allergic reactions, asthma, parasitic infections, and certain autoimmune or hematologic disorders. It aids clinicians in understanding the immune response and guides treatment decisions based on eosinophil levels.
