🔬 What is the Test?
The Absolute Eosinophil Count (AEC) Test measures the number of eosinophils, a type of white blood cell (WBC) that plays a key role in allergic reactions, parasitic infections, and immune system responses.
📊 Normal Ranges:
Adults & Children: 100 - 500 cells/µL
Mild Eosinophilia: 500 - 1,500 cells/µL
Moderate Eosinophilia: 1,500 - 5,000 cells/µL
Severe Eosinophilia: > 5,000 cells/µL (May indicate serious conditions)
🩺 Purpose of the Test:
✅ Diagnose and monitor allergic reactions (asthma, hay fever, eczema)
✅ Identify parasitic infections (roundworms, hookworms, etc.)
✅ Assess autoimmune disorders and inflammatory diseases
✅ Monitor eosinophilic disorders (eosinophilic esophagitis, hypereosinophilic syndrome)
✅ Evaluate blood cancers (leukemia, lymphoma, etc.)
🧪 When is it Recommended?
🔹 Unexplained allergic reactions, rashes, or asthma symptoms
🔹 Chronic cough, nasal congestion, or difficulty breathing
🔹 Persistent digestive issues linked to eosinophilic disorders
🔹 Unexplained high WBC count in a complete blood count (CBC) test
📝 How is the Test Done?
1️⃣ A blood sample is drawn from a vein.
2️⃣ The lab calculates AEC from total WBC & eosinophil percentage.
3️⃣ Results help diagnose allergies, infections, or blood disorders.
⚠️ What Do Abnormal Results Mean?
📈 High AEC (Eosinophilia):
Allergic disorders (asthma, eczema, rhinitis)
Parasitic infections (intestinal worms, filariasis, schistosomiasis)
Autoimmune diseases (lupus, inflammatory bowel disease)
Certain cancers (Hodgkin’s lymphoma, leukemia)
📉 Low AEC:
Not clinically significant in most cases
May be due to stress, steroid use, or normal immune variation
