We are not tied to a manufacturer and use the best system for you, although the video from a good provider shows the scientific care used in patch testing.
Patch testing is a valuable method for diagnosing allergic skin diseases. Small amounts of suspected allergens are applied to your skin in a controlled way, any reaction you have is then assessed by one of our consultant dermatologists.
We can all have passing reactions to allergens on our skin but for some people, common substances cause debilitating conditions. Allergy patch testing in our London clinic helps find the cause.
This could be hair dye, or make up you are using, unknown exposure at work, or in any environment you visit. The advantage of patch testing is not having to be there, you are able to test the substance without the context.
Patch Testing Procedure
Tiny amounts of suspected allergens are applied to your skin using non allergic, adhesive patches, often on your back. Two days later, the patches are removed and your skin reaction assessed for evidence of an allergic reaction.
A second assessment will take place after a further two days. Normally the final reading, although there can be cases where we want to examine you a third time, for reactions known to take longer to develop.
There are also variations of patch testing we use occasionally. Photopatch testing can help diagnose an allergic reaction to substances when your skin is also exposed to sunlight, atopic patch testing helps track down food allergies.
The latter can bring symptoms akin to eczema, or dermatitis, often in children. For all ages, patch testing helps find a specific cause, for what may have seemed to be a naturally occuring condition.
Benefits Of Testing
Knowing what you are allergic to can eliminate a skin problem, or hold the key to managing your condition. Combined with the experience of a skilled dermatologist, patch testing often provides answers.
This is also a low risk, minimally invasive procedure, suitable for all ages and skin types. A wide range of substance reactions can be tested, from chemicals at work, to cosmetics, to apparently safe household items.
We provide patch testing in London as an essential dermatology tool, to support our patients and help to eliminate their skin conditions.
