A patch test is a skin allergy test that helps detect substances causing delayed allergic reactions when in contact with your skin. Unlike other allergy tests, it focuses on contact-based allergens that are common in everyday products.

Patch testing is often 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 evaluates reactions over several days

This method identifies allergies that may not appear immediately.
