Patch Testing for skin allergies

patch testing for dermatitisHealthcare Inspectorate WalesAre you suffering from inflammation of your skin causing discomfort and skin rashes (allergic contact dermatitis) ?

Allergic Contact Dermatitis is a condition where you develop patches of dermatitis (eczema) when your skin reacts against a specific substance. The patches of dermatitis are areas of skin which are itchy, red and inflamed. They may also blister. The substance that you react to is called an allergen. You are not born with this type of allergy, but will have previously come into contact with the allergen which has sensitised your immune system. For reasons not fully understood the body starts to react when it comes into further contact.

Why have a patch test?

If you know what you are allergic to you can try to avoid contact with substances or objects that contain the allergen. However some people develop dermatitis and the cause is not clear. Patch Testing may help to identify the substance(s) causing your allergy. Although it is not a foolproof test to find every cause of dermatitis, it often helps.
How is patch testing undertaken?
On day one of testing, tiny amounts of 25 or more substances are applied as small patches to your skin, usually on the upper back. They are fixed on with non-allergic tape. After two days you return to The Clear Skin Dermatology Treatment Clinic and the patches are removed, checked for reaction, and further patches may be added. On day five the skin is examined to see if there is a reaction to any of the tested substances. From the results of these tests our dermatologist can then best advise how to prevent further outbreaks of dermatitis.
