A patch test is a skin allergy test used to identify substances that cause delayed allergic reactions when they come into contact with your skin. Unlike other allergy tests, it focuses on contact-based allergens found in everyday products.

It is 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 evaluates reactions over several days

This helps detect delayed allergic responses effectively.
