Frequently Asked Questions
Why is Allergy Screening IgE With PhadiaTop (Child Below 5 y) Test Done:
- 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.
What does Allergy Screening IgE With PhadiaTop (Child < 5 y) measure?
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.
What to expect during Allergy Screening IgE With PhadiaTop (Child < 5 y) test?
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
What are the normal levels of Allergy Screening IgE With PhadiaTop (Child < 5 y)
Negative: < 0.35 PAU/L
Positive: >= 0.35 PAU/L
What if Allergy Screening IgE With PhadiaTop (Child < 5 y) results are Present/ Absent?
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.
An allergy is a hypersensitivity disorder of the immune system that causes undesirable reactions to certain substances like food, dust, pollen, drugs or even animal dander. These reactions normally do not occur in others. The substance causing the reaction is an allergen. Immunoglobin E is an antibody that the body produces in case of an allergic reaction. Total IgE test is a blood test used to measure the complete IgE levels in the blood, but it does not indicate what is the specific allergen causing the reaction. Phadiotop is an allergy screening test that uses ImmunoCAP with comprehensive inhalant allergens like pollen, animal dander, grass, weed etc. It is a highly specific and sensitive test for detecting inhalant allergies. It differentiates atopic from non-atopic cases. Phadiatop Infant is a multi-allergen screening semi-quantitative test for the detection of IgE antibodies and has well-balanced mixture of allergens utilizing cross-sensitizing & co-sensitizing allergen groups (recommended for children upto 4 years 11 months)
