Main types of skin tests<\/h3>\n
A drop of allergen is applied to the skin, after which a light puncture is performed through the drop. The method is effective in cases of suspected inhalation or food allergy. Assessment is done after 15\u201320 minutes.<\/p>\n
The allergen is applied to the skin through a micro-scratch. This method is less sensitive, but is used in some cases for household and seasonal allergens.<\/p>\n
Allergen patches are applied to the back. The samples are not removed for 48 hours. It is used when contact dermatitis, reactions to cosmetics, metals or chemicals are suspected.<\/p>\n
The allergen is injected into the skin. It is used in more complex clinical cases, in particular to detect drug allergies.<\/p>\nSkin test comparison table<\/h3>\n
