Absolute Eosinophil Count (AEC)

The Absolute Eosinophil Count (AEC) is a vital diagnostic tool because it quantifies the specific number of eosinophils—a type of specialized white blood cell—circulating in your bloodstream, offering a clearer picture of immune health than a simple percentage can provide. By pinpointing whether these levels are abnormally high (eosinophilia) or low, the test helps clinicians distinguish between routine infections and more complex underlying conditions such as allergic reactions, asthma, parasitic infections, or autoimmune disorders.
