Testing & Diagnosis for Animal Allergy in Children

Tests

How are allergies diagnosed?

All tests measure your child's level of Immunoglobulin E (IgE) antibodies to specific allergens.

Skin test

Using diluted solutions of specific allergens, the physician either injects your child with the solutions or applies them to a small scratch or puncture. Reaction appears as a small red area on the skin.

Skin tests provide faster results and are more specific than blood tests.

Blood test

A RAST (radioallergosorbent test) will analyze the level of antibodies in your child's bloodstream.
