The Absolute Eosinophil Count (AEC) test is a blood test that measures the number of eosinophils, a type of white blood cell, in a person’s blood. Eosinophils are involved in the body’s immune response and are often elevated in certain diseases such as allergies, parasitic infections, and certain types of cancer.

Pre-test preparation:

No special preparation is usually required for this test.

Testing method:

A small sample of blood is taken from a vein in the arm using a needle and syringe.
The blood sample is sent to a laboratory for analysis.

Common Symptoms for prescribing this test:

• Itchy skin, rash, or hives
• Shortness of breath
• Swelling of the face, lips, tongue, or throat
• Persistent or recurring infections
• Abdominal pain
• Diarrhea
• Fatigue
• Unusual weight loss

Diagnosis:

The AEC test is often used to help diagnose conditions such as allergies, asthma, and parasitic infections.

It can also be used to monitor the effectiveness of treatment for these conditions.

Reference range:

The reference range for AEC varies depending on the laboratory that performs the test.

Typically, a normal AEC is between 150 and 450 eosinophils per microliter of blood.

However, it is important to note that the reference range can vary depending on the lab that performed the test and the patient’s age, sex, and overall health.

Normal values:

AEC values between 150 and 450 eosinophils per microliter of blood are considered normal in most laboratories.

It is important to consult with a doctor or healthcare professional for any questions or concerns regarding the AEC test or any other medical test.
