Absolute Eosinophil Count (AEC) is a blood test that measures the actual number of eosinophils, a type of white blood cell involved in allergic reactions and defense against certain infections. The test is needed to evaluate conditions associated with increased eosinophils, such as allergies, asthma, parasitic infections, and some inflammatory or blood disorders. It can also help monitor disease activity and response to treatment when clinically indicated.
Eosinophils are white blood cells that participate in immune responses, particularly those associated with allergies, inflammation, and certain parasitic infections.
A high AEC, called eosinophilia, may occur with allergies, asthma, parasitic infections, medication reactions, skin conditions, autoimmune disorders, or certain blood-related diseases.
A low eosinophil count is usually not considered clinically significant by itself and may occur normally or during certain infections, stress responses, or corticosteroid treatment.
Eosinophilia refers to an abnormally increased number of eosinophils in the blood. The significance depends on the degree of elevation and the underlying clinical situation.
Yes. Allergic conditions such as allergic rhinitis, eczema, and some forms of asthma can cause an elevated eosinophil count.
