Patch Testing in Shrewsbury

Patch testing is a specialist procedure carried out to find out whether your skin condition is caused or aggravated by an allergy to substances which have come into contact with your skin. This is called contact allergy which is a ‘Type 4 allergy’. Substances that cause an allergic reaction are called allergens and they can be found both at home and work.

Patch testing is arranged when appropriate after an initial consultation with one of our specialist dermatologists. Our patch testing service is run by consultant dermatologist Dr Niki Hart.

Patch testing is not used to investigate food allergy or other ‘Type 1 allergies’ such as to dust, pollen and animals.

You will need to attend for appointments on Monday, Wednesday and Friday.

On your first visit we will review your history and discuss your work and social activities, before choosing appropriate allergens to test. A nurse will then apply several small discs containing the substances to be tested and attach the ‘patch’ to your back using hypoallergenic tape.

The substances will remain taped in place for 48hrs or until your second visit to the nurse, when they will be removed, and any reactions are noted. Additional patches may be applied at this visit

On the third visit your back will be examined by your consultant dermatologist who will discuss any reactions with you.

The skin patches are applied to your back for practical reasons. It is the biggest surface area of skin and the patches are more likely to stay in contact there, but we do occasionally use upper arms.
