It felt like as soon as I shared my three month old’s eczema diagnosis with family and friends everyone was telling me to get him allergy tested. Being a pharmacist I knew about allergy testing but I needed to find out how it could help me manage my baby’s eczema. A whole new chapter was waiting for me and my eczema baby.

Children with eczema are more likely to be allergic to things they eat, touch, or breathe in and allergy tests can identify these things (allergens) that cause allergic reactions. Allergy testing gives you information which can help you manage your child’s eczema.

Finding out what your eczema child is allergic to means that you can better control their eczema by avoiding these allergens. What is confusing is that taking these foods out of your eczema child’s diet doesn’t mean their eczema is cured, but helps you to better manage their eczema by avoiding them.
Many eczema children with moderate to severe eczema will have immediate allergies to certain foods. Reactions can include hives, difficulty breathing and swelling and is called anaphylaxis.
what do allergy tests do for for eczema child?
Allergy testing can help you manage your child’s eczema. Allergy testing is done by skin prick testing or blood tests which helps your doctor work out what your eczema child is allergic to and then can give you advice on what allergens you should avoid.
what do allergy tests involve?
skin prick testing
The most common type of allergy testing is skin prick testing. Generally speaking your doctor will write numbers on your eczema child’s forearm which correspond to an allergen. The skin is pricked with a small needle which has a small amount of the allergen on it. If your eczema child is allergic to the allergen within about 15 to 20 minutes an itchy, red lump will appear. This itchy, red lump usually goes away within a couple of hours.
Blood tests are usually done if your eczema child’s skin means that skin prick testing isn’t an option, or if your eczema child is taking medication, like an antihistamine, which could interfere with the results of the skin prick testing.
The Australasian Society of Clinical Immunology and Allergy have more information on different types of allergy testing.
