A patch test is a skin allergy test that identifies substances causing delayed allergic reactions when in contact with your skin. Unlike other allergy tests, patch testing focuses on allergens that are often found in everyday products.

Patch tests are commonly used to diagnose:

• Allergic contact dermatitis
• Cosmetic and skincare allergies
• Occupational skin reactions
• Chronic eczema triggers

How Does Patch Testing Work?

The procedure is simple and non-invasive:

1. Small amounts of allergens are applied to patches
2. Patches are placed on your back
3. You wear them for 48 hours
4. Your allergist checks for reactions over several days

This method helps detect delayed allergic responses that might not be immediately obvious.
