Description
EDTA WB, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
The AEC test requires a blood sample, which is collected in a purple vaccutainer (test tube). A healthcare professional will collect a small amount of blood from a vein in your arm using a needle and syringe.
Test Time:
The test time for the AEC test varies depending on the laboratory and the specific testing method used. Generally, results can be available within a few hours to a day.
AEC Test Normal Range:
The normal range for the absolute eosinophil count may vary slightly depending on the laboratory and the reference values used. Here is the reference table for AEC test normal values:
| Parameter | Normal Range |
| Absolute Eosinophil Count (AEC) | 30 to 350 esinophils/μL of blood (cells/μL) |
| Hemobglobin (Hb) | Varies by age and gender. Common range for adult males: 13.8 to 17.2 g/dL;
adult females: 12.1 to 15.1g/dL |
| White Blood Cell Count (WBC) | 4500 to 11000 cells/μL of blood |
| Platelet Count | 1,50,000 to 4,50,000 platelets/μL of blood |
| Red Blood Cell Count (RBC) | 4.5 to 6.0 million cells/μL for adult males
4.0 to 5.5 million cells/μL for adult females |
| Hematocrit (Hct) | Varies by age and gender. Common range for adult males: 38.3% to 48.6%;
adult females: 35.5% to 44.9% |
| Mean Corpuscular Volume (MCV) | 80 to 100 femtoliters(fL) |
| Mean Corpuscular Hemoglobin (MCH) | 27 to 33 picograms(pg) |
| Mean Corpuscular Hemoglobin Concentration (MCHC) | 32% to 36% g/dL |
What is AEC test?
The AEC test measures the absolute count of eosinophils in the blood. Eosinophils are a type of white blood cell involved in the immune response against certain infections and allergic reactions. Elevated or decreased levels of eosinophils can indicate various medical conditions.
Test Procedure:
During the test, a blood sample is collected from a vein in your arm. The collected sample is sent to a laboratory where it is analyzed to determine the absolute count of eosinophils using automated cell counting techniques.
When to take the test:
The AEC test is commonly used to evaluate and monitor conditions such as allergies, asthma, parasitic infections, autoimmune diseases, and certain types of cancers. Your healthcare provider may order this test if you have symptoms suggestive of these conditions or as part of routine blood work.
Who should take this test:
The AEC test may be recommended by your healthcare provider if you have symptoms or a medical history that suggests eosinophil-related disorders. It is commonly used in patients with asthma, allergic rhinitis, dermatitis, suspected parasitic infections, or those undergoing evaluation for systemic diseases.
Precautions for exceptional cases (pregnancy etc.):
Pregnancy itself does not significantly affect the AEC levels. However, if you are pregnant and undergoing the AEC test, it is important to inform your healthcare provider about your pregnancy status. They will consider other factors and interpret the test results accordingly.
FAQs for AEC Test:
Q1: What happens if AEC is high?
A: An elevated AEC may indicate various conditions, such as allergies, asthma, parasitic infections, autoimmune diseases, and certain types of cancers. Your healthcare provider will interpret the results in the context of your medical history and symptoms to determine the underlying cause.
Q2: Can medications affect AEC test results?
A: Certain medications, such as corticosteroids and antihistamines, can affect AEC levels. It is important to inform your healthcare provider about all the medications and supplements you are taking before the test.
Q3: Is fasting required before the AEC test?
A: Fasting is generally not required for the AEC test. It can be performed at any time of the day.
Q4: Can a single AEC test provide a definitive diagnosis?
A: A single AEC test alone is not sufficient for a definitive diagnosis. It is often used as a part of a comprehensive evaluation, including medical history, physical examination, and other diagnostic tests.
Q5: Can AEC levels fluctuate over time?
A: Yes, AEC levels can fluctuate based on various factors, including underlying conditions, medications, and the body’s immune response. It is important to interpret the results in the context of your overall clinical presentation.
Q6: What is the difference between a CBC and AEC test?
A: A CBC (Complete Blood Count) is a broader blood test that measures various components of blood, including red blood cells, white blood cells, and platelets. AEC, on the other hand, specifically measures the number of eosinophils, which are a type of white blood cell. AEC is often used to detect and monitor conditions related to eosinophilic disorders, allergies, and parasitic infections.
Q7: What causes high AEC?
High AEC levels can result from:
- Allergies (allergic rhinitis, eczema)
- Asthma
- Parasitic infections (e.g., roundworms, hookworms)
- Autoimmune diseases (e.g., eosinophilic granulomatosis with polyangiitis)
- Certain medications
- Blood disorders (e.g., eosinophilic leukemia)
Q8: How can I reduce eosinophils naturally?
A: Reducing eosinophil levels often involves addressing the underlying cause. To manage eosinophilia (high eosinophil count):
- Follow your healthcare provider’s treatment plan.
- Manage allergies with antihistamines and avoidance measures.
- Treat underlying infections if present.
- For severe cases, your healthcare provider may prescribe medications like corticosteroids.
Q9: What not to eat in eosinophilia?
A: If you have eosinophilic disorders triggered by food allergies, you should avoid foods that you are allergic to. Common food allergens include nuts, shellfish, dairy, eggs, and soy. Consult an allergist or immunologist for specific dietary recommendations based on your allergies.
* It’s important to remember that elevated AEC is a marker, and the underlying condition needs to be diagnosed and treated by a healthcare provider. Please consult your healthcare provider for personalized guidance and treatment options if you have concerns about your AEC levels.
