How is it done?

There are two main types of allergy tests:

Blood test

A small sample of blood will be taken from a vein in your child's arm. The sample can then be tested in a laboratory for allergy or asthma triggers such as food (milk, eggs, soya, nuts, wheat or fish) or pollen, mould and pet fur. The level of IgE (immunoglobulin E), a chemical naturally released during an allergic reaction, will also be measured.

The results should tell you what your child is allergic to. Results can take a few weeks.

Skin prick test

A tiny amount of allergen (the substance you think is causing the allergy) is put onto the skin to see if there is a reaction. Several allergens can be tested at the same time. You'll get the results within 30 minutes.
