Information for Participants

The questionnaire is divided into three parts:

Patch test
The patch test is a specific test for the diagnosis of contact allergies. It consists of patches kept on the skin for 48 hours, and then removed. After 24 hours from removal, an experienced dermatologist will inspect the area of application to identify a skin reaction to any of the applied substances. These will be substances that come into contact with the skin in everyday life, and that are present in objects of common use, such as metals or fragrances. These substances do not cause any adverse reactions in most people. A positive test is characterised by the presence of reddening and localised itching.
A total of 50 allergens (6 patches) will be patch tested.
