Absolute Eosinophil Count Test
Eosinophils are a type of white blood cell that plays a crucial role in your immune system. These cells help defend your body against foreign substances and fight off diseases. Think of them as your body's little soldiers, working to combat invading bacteria, viruses, and infections. They are produced regularly in the bone marrow, and when your body faces an infection or disease, their numbers increase. Once activated, eosinophils travel to the affected area to help eliminate the threat.
What is an AEC test?
The Absolute Eosinophil Count (AEC) blood test measures the number of eosinophils, white blood cells that play a key role in your immune system. These cells help protect the body by managing allergic responses and fighting infections.
If your AEC levels are elevated, it could suggest conditions like severe allergies, parasitic infections, or even certain types of cancer. On the flip side, a low AEC count might point to infections or bone marrow disorders. Doctors usually recommend this test when symptoms suggest possible allergies or parasitic infections.

Get A Second OpinionWhen Should You Get The AEC Test Done?
Doctors typically recommend an Absolute Eosinophil Count (AEC) if they detect unusual eosinophil levels during a white blood cell differential test, which is often done alongside a complete blood count (CBC). A CBC helps evaluate the different types of white blood cells in the blood and can reveal underlying health issues.
The AEC test can show if a person has an abnormally high or low white blood cell count, which may signal various diseases. Healthcare providers may order this test if they suspect conditions such as severe allergies, medication reactions, or parasitic infections.
Uses of AEC Test
The Absolute Eosinophil Count (AEC) test is a valuable tool for diagnosing and monitoring various health conditions. Here are some of its key uses:
- Diagnosing Allergies: The AEC test is commonly used to detect allergic conditions. High eosinophil levels in the blood can indicate allergies such as asthma, allergic rhinitis, and more.
- Monitoring Allergic Reactions: Once an allergy is diagnosed, the AEC test helps track how well the body is responding to treatment. A lower eosinophil count can suggest improved management of the allergy.
- Detecting Parasitic Infections: Eosinophils often respond to parasitic infections. This test is useful in identifying such infections by detecting elevated eosinophil levels.
- Assessing Eosinophilic Disorders: Conditions like eosinophilic esophagitis or eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome) can cause unusually high eosinophil counts. The AEC test aids in diagnosing and monitoring these disorders.
- Screening for Cancer: Elevated eosinophil levels may sometimes signal the presence of certain cancers. The AEC test, in combination with other diagnostic tools, can help rule out malignancies.
How to Prepare for the AEC test?
Preparing for the AEC test can make the experience smoother. Here are some helpful tips to get ready:
- Consult Your Healthcare Provider: Before your AEC test, it's essential to have a conversation with your healthcare provider. They can give you specific instructions on how to prepare, which medications to start or stop, and any other important information.
- Stay Hydrated: Being well-hydrated is key before a blood test, as it makes it easier for the phlebotomist to find a vein. Just be careful not to overhydrate, as that can dilute your blood.
- Choose Comfortable Clothing: Wear loose-fitting clothes to your appointment. This makes it easier for the phlebotomist to collect samples without any hassle.
- Follow Specific Instructions: Your healthcare provider may have tailored instructions based on your health history, such as fasting or timing. It's crucial to follow these guidelines closely to ensure accurate test results.
What happens in an Absolute Eosinophil Count Test?
During an absolute eosinophil count (AEC) test, a blood sample is collected from a vein in the arm using a needle and taken to a lab for analysis. In the laboratory, the blood sample is analyzed using an automated machine called a hematology analyzer, which counts the number of eosinophil cells present in the blood. The results of the AEC test are typically reported in cells per microliter (μL) of blood.

Book an AppointmentAbsolute Eosinophil Count Test Results
An absolute eosinophil count (AEC) test results are reported as the number of eosinophil cells per microliter (μL) of blood. Normal AEC ranges can vary slightly depending on the laboratory that does the test but generally falls within the following ranges:
- Adults: 30 to 350 cells/μL
- Children: 50 to 500 cells/μL
An elevated AEC may indicate an allergic reaction, a parasitic infection, or certain cancers. The severity of the elevation may provide additional information on the severity of the condition. A low AEC may indicate certain types of infections or bone marrow disorders. As with an elevated AEC, the severity of the decrease may provide additional information on the severity of the condition. A healthcare provider should interpret AEC test results, as results must be considered in the context of the patient's medical history, symptoms, and other diagnostic tests.
Risk factor of Absolute Eosinophil Count (AEC) Test?
- Allergic reactions
- Parasitic infections
- Certain cancers
- Autoimmune disorders
- Bone marrow disorders
Frequently Asked Questions
How is the AEC test performed?
The AEC test is performed by collecting a blood sample from a vein in the arm. The blood sample is then sent to a laboratory for analysis using an automated machine called a hematology analyzer.
Is there any preparation required before the AEC test?
Generally, no special preparation is required for the AEC test. However, patients should follow any instructions provided by their healthcare provider or laboratory, such as fasting before the test or avoiding certain medications that may affect the results.
Is the AEC test painful?
The AEC test involves a needle stick to collect the blood sample, which may cause mild discomfort. However, most people tolerate the test well; discomfort typically subsides quickly.
How long does it take to get AEC test results?
The time it takes to get AEC test results can vary depending on the laboratory conducting the test and the specific circumstances of the test. However, in general, results are usually available within a few days.
What are the risks associated with the AEC test?
The AEC test is a safe and routine blood test. However, as with any blood test, there is a slight risk of bleeding, bruising, or infection in the area where the needle is inserted. These risks are typically very low and can be minimized by following the healthcare provider's or laboratory's instructions.
Can the AEC test be done at home?
No, the AEC test cannot be done at home. It must be performed by a healthcare provider or in the laboratory using specialized equipment and techniques.
What is the normal range for absolute eosinophils?
The normal range for absolute eosinophil count (AEC) in peripheral blood is typically 0 to 500 cells/microL or less than 0.5 x 10^9/L. However, it's important to note that normal ranges may vary slightly depending on the laboratory performing the test and the population being tested.
What are the symptoms of high eosinophils?
Symptoms of high eosinophils include weight loss, fevers, night sweats, fatigue, cough, chest pain, swelling, stomachache, rash, pain, weakness, confusion, and coma.
What is the cost of the AEC test?
The cost of the AEC test is approximately Rs. 100 to Rs. 300, but it can vary from place to place.
Where can I get the AEC test?
You can get an AEC test at Medicover Hospitals.
