About The Test
What Is the Absolute Eosinophil Count (AEC) and Why Is It Important?
The Absolute Eosinophil Count (AEC) is a blood test used to measure the number of eosinophils in the
blood. These are white cells that belong to a group called granulocytes. Eosinophils belong to one
category referred to as granulocytes and are vital players in the body’s immune system especially when it comes to fighting parasites and allergic reactions.
It is an uncomplicated and rapid test done through flow cytometry or automated counting. Thereafter, using special equipment like microscopes, such cells are analysed by being passed through them.
What Does the Absolute Eosinophil Count (AEC) Measure?
The count is measured per cubic millimetre of blood. For this reason, these measurements serve doctors well during diagnosis and follow-up of conditions with abnormal counts.
When Is the Absolute Eosinophil Count (AEC) Usually Taken?
The AEC is mostly done to:
1. Detect and follow the course of diseases such as asthma, allergic reactions, and parasitic infections
2. Monitor response to treatment in conditions where eosinophils are raised
3. Determine causes for unexplained symptoms including fatigue, fever or weight loss among other signs
Are There Any Risks or Limitations to the Absolute Eosinophil Count (AEC)?
Although relatively safe test, the AEC carries minimal risk of:
1. Bleeding or bruising at the site where blood was drawn
2. Infection
3. Allergic reaction to equipment/materials used for testing
Limitations of the AEC test include:
1. Different eosinophil counts may occur for example; at different times of day, during stressful situations and while taking particular medications.
2. A test may either fail to show significant results or may fail to detect other underlying medical conditions unrelated to irregular eosinophils.
3. There might be a failure by this procedure in detecting some situations which do not cause abnormal levels of eosinophils.
List of Parameters
What Parameters Are Evaluated in the Absolute Eosinophil Count (AEC)?
1. The thousands of eosinophils/mm3
2. Eosinophils in peripheral blood smear: 1-6% of total WBC count.
Why This Test
Who Should Consider Taking the Absolute Eosinophil Count (AEC)?
The Aim Group Reviews suggests that absolute eosinophil count test is for you if you:
- Have symptoms related to allergies or parasitic infections;
- Have a family history of conditions with eosinophilia;
- Take medication that may affect your eosinophil counts.
Benefits

2. Assessing how well treatment for such conditions, like asthma, is working;
3. Detecting possible health problems early on.
What Conditions Can the Absolute Eosinophil Count (AEC) Diagnose?
This will help diagnose diseases/conditions such as:
1. Allergies
2. Asthma
3. Eosinophilic pneumonia
4. Parasites
5. Inflammatory bowel disease.
Test Preparation
Preparing for Your Absolute Eosinophil Count (AEC)
People who are scheduled to have this test are advised to do these things:
1. Follow any specific instructions given by their healthcare provider
2. Avoid doing strenuous activity, being stressed out or taking certain medications before going for the test.
3. It could be either fasting or non- fasting as per the requirements of the test.
Pre-requisites: A medical doctor’s recommendation.
Eligibility: Everybody with a condition or symptom that necessitates an eosinophil count
Procedure for Taking the Test A needle and syringe are used to draw a blood sample from a vein in the arm.
Caution before taking test: Notify your healthcare provider if you have any drug reactions, have ever had complications with bleeding.
Test Results
Understanding Your Absolute Eosinophil Count (AEC) Results
Condition/Findings | Explanation | Conclusion |
---|---|---|
Eosinophilia | An absolute eosinophil count higher than 500 cells/μL | Indicates increased numbers of eosinophils; may be related to asthma, allergic reactions, or parasitic infections. |
Normal Eosinophil Count | An absolute eosinophil count ranging from 0 to 400 cells/μL | Indicates normal levels of eosinophils in the blood. |
Eosinopenia | An absolute eosinophil count below 0 cells/μL | Indicates reduced numbers of eosinophils; may be associated with bone marrow failure or autoimmune diseases. |
FAQs
What are the normal limits for an absolute eosinophil count?
Normal limits for an absolute eosinophil count are between 0 and 400 cells/μL.
What is meant by “eosinophilia?”
A higher than usual number of eosinophils as seen in your blood sample, probably over five hundred per microlitre.
How long does it take to get the results of an AEC?
Usually, you will have access to them after a few hours or by next business day.
Can I take prescription before the examination?
Inform your doctor of any prescribed and non-prescribed medicines you might be taking prior to undergoing AEC test as some medications can affect results.
