FAQs

What is patch testing?

Patch testing is a diagnostic procedure where small amounts of common allergens are applied to patches placed on your back. They are left in place for 48 hours to see if your skin develops a localized allergic reaction, identifying the culprit substance.

How long does a skin allergy reaction take to appear?

Allergic contact dermatitis is a delayed hypersensitivity reaction, meaning a rash may not appear until 24 to 72 hours after exposure to the allergen.
