Frequently Asked Questions
What does AEC measure?
AEC counts the exact number of eosinophils — a type of white blood cell involved in allergic responses and parasitic infections — per microliter of blood.
What is a normal AEC range?
Normal AEC is typically 0–450 cells/μL in adults. Values above 500/μL indicate eosinophilia and require clinical correlation.
What causes high AEC?
Elevated AEC is commonly seen in allergic conditions (asthma, hay fever, drug reactions), parasitic infections, autoimmune disorders, and certain hematologic conditions.
What causes low AEC?
Low eosinophil count may occur during acute stress, bacterial infections, or with corticosteroid therapy. It is generally less clinically significant than eosinophilia.
Is fasting required for AEC test?
No, fasting is not required for Absolute Eosinophil Count. Sample can be collected at any time of day.
How is the sample collected?
A small blood sample is drawn from the vein in your arm into an EDTA (purple-top) tube. Results are available within 24 hours via www.drpatholab.in or WhatsApp/Email.
