Allergy AlaTOP-Pediatric, in Visit Clinic

A positive Phadiatop means the blood test detected specific IgE antibodies to one or more common inhalant allergens. It indicates sensitization and supports an allergic cause for respiratory symptoms (rhinitis/asthma) but does not prove clinical allergy by itself. Clinical correlation and follow-up testing (individual specific-IgE or skin-prick testing) are usually required to identify the responsible allergen and guide treatment.

There are four common allergy types: food allergies (e.g., peanuts, shellfish) causing hives, vomiting or anaphylaxis; drug allergies (e.g., penicillin) causing rashes or severe reactions; insect‑sting allergies (bees, wasps) causing swelling or anaphylaxis; and environmental/seasonal allergies (pollen, dust mites, pet dander, mold) causing hay fever, sneezing, itchy eyes and asthma exacerbations.

The most common allergy in children is food allergy, with cow’s milk allergy the most frequent in infants and young children. Eggs and peanuts are also common triggers. Symptoms range from skin rashes and hives to vomiting, wheeze, or anaphylaxis in severe cases. Many children outgrow milk and egg allergies, but peanut and tree‑nut allergies often persist and require long‑term management.

A child should see an allergist as soon as allergy symptoms are severe, recurrent, or affect breathing, eating, sleep, or growth. Seek urgent specialist care for suspected anaphylaxis or severe food reactions. Early referral is recommended for infants with suspected food allergy or persistent eczema and for children with recurrent wheeze/asthma, chronic rhinitis, or multiple reactions so diagnosis and management can begin.

IgE is an antibody class; clinicians measure total IgE or specific IgE antibodies to individual allergens. Phadiatop is a laboratory screening test that measures specific IgE to a panel of common inhalant allergens and reports a combined positive/negative result. Phadiatop screens for atopic sensitization to airborne allergens but isn’t a total-IgE test and positive results usually prompt further single-allergen testing.

Very high IgE levels often indicate allergic or parasitic processes and can accompany atopic dermatitis, allergic asthma, or chronic sinus disease. Extremely elevated IgE may reflect rare immune disorders (e.g., hyper‑IgE syndrome) and associate with recurrent infections, severe eczema, wheeze, and increased allergy/anaphylaxis risk. Evaluation by a clinician, allergy testing, and treating the underlying cause are recommended.
