Allergy Screen IgE with PhadiaTop (For Children < 5 Years) – Detailed Guide

The Allergy Screen IgE with PhadiaTop test is a blood test used to detect allergic sensitization in young children (<5 years old). It measures the levels of Immunoglobulin E (IgE), a type of antibody involved in allergic reactions, and screens for common allergens that may affect children.

✅ Food Allergies – Common triggers: Milk, eggs, peanuts, soy, wheat, nuts, seafood
✅ Airborne Allergies (Inhalants) – Dust mites, pollen, mold, pet dander
✅ Eczema (Atopic Dermatitis) – To check for allergic triggers

Understanding Test Results

🔬 PhadiaTop IgE Screening

• The test screens for a panel of common allergens in children
• If positive, specific IgE tests may be needed to identify the exact allergen

🔴 High IgE Levels May Indicate:

• Food allergies (milk, eggs, nuts, wheat, soy)
• Environmental allergies (dust, pollen, mold, pet dander)
• Asthma or eczema
• Parasitic infections (rare cause of high IgE)

🟢 Low or Normal IgE Levels

• No significant allergic sensitization detected

Next Steps If IgE Is High?

🔬 Further Tests May Be Needed:

• Specific IgE Test (RAST or ImmunoCAP) – Identifies exact allergens
• Skin Prick Test (SPT) – If further confirmation is needed
• Elimination Diet & Oral Challenge – For food allergies

✅ Management & Treatment:

• Avoidance of identified allergens
• Antihistamines or allergy medications
• Immunotherapy (Allergy Shots) for severe cases
