Allergy Screening IgE With PhadiaTop (Child < 5 y)

• Helps in screening and detecting allergies.
• Measures the overall quantity of immunoglobulin E in the blood, not the amount of a specific type.
• Antigen-specific IgE can help to identify the responsible allergen.It may also be done in cases of suspected inhalant allergies for further diagnosis.

The common symptoms are:

• Itching
• Running nose, sneezing, coughing
• Diarrhoea
• Hives
• Certain severe cases may also lead to anaphylactic shock.

The test is used to screen for possible allergies due to pollen, animal dander, trees, grass, weed, mite, insects etc. Based on these results further specific testing is recommended.

This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer

Negative: < 0.35 PAU/L
Positive: >= 0.35 PAU/L

A positive result confirms the presence of atopic allergy and must be followed by more specific testing to identify the causative allergen. A negative result indicates that the symptoms are not due to common food and inhalant allergies and other differential diagnoses must be considered. High IgE levels are found in asthma, allergic bronchopulmonary aspergillosis, primary immunodeficiency, parasitic infections, inflammatory diseases and some cancers. Low IgE levels may be seen in auto-immune disorders.
