Absolute Eosinophil Count (AEC) Test

The Absolute Eosinophil Count (AEC) test measures the number of eosinophils, a type of white blood cell, in the blood. Eosinophils play a crucial role in the body’s immune response, particularly in allergic reactions, parasitic infections, and certain inflammatory conditions. This test helps diagnose conditions like allergic disorders, asthma, parasitic infections, autoimmune diseases, and some blood disorders.

A high eosinophil count (eosinophilia) may indicate allergic conditions (such as asthma, hay fever, or eczema), parasitic infections, autoimmune diseases, or certain cancers like leukemia. A low eosinophil count is usually not concerning but can occur due to stress, excessive steroid use, or severe infections. Doctors often recommend this test for individuals experiencing chronic allergies, unexplained fever, rashes, breathing difficulties, or symptoms of parasitic infections.
