What is Contact Dermatitis Patch Testing?

Contact dermatitis is when the skin becomes itchy and inflamed after coming into contact with a substance that triggers an allergic reaction. 80% of those affected have the type that causes a reaction in the skin cells, versus an immune response. Almost everyone gets contact dermatitis at least once in their lives. If you can identify and avoid the irritant causing the reaction, the rash usually clears on its own. However, you could continue to suffer without the proper help while you try and figure it out. Texas Dermatology proudly offers a comprehensive solution through contact dermatitis patch testing. If you have chronic, itchy skin here’s why you may want to consider it.

What is Contact Dermatitis Patch Testing?

The test helps identify which substances are causing the allergic reaction on your skin. This includes jewelry, clothing, ingredients in products, and exposure to chemicals and substances we encounter throughout our day. The contact dermatitis patch test measures your reaction to over 80 different ingredients, chemicals, and metals. It can be performed on adults and children.

The test begins by placing patches on the skin that contain small amounts of allergens that commonly cause skin reactions. The patches are typically left in place for several days. Your dermatology practitioner then examines the areas to determine which allergens are causing a skin reaction. Once irritants are identified, all causes of dermatitis are then treated. Better yet, you will know what you should avoid, thus preventing further recurrences. Contact dermatitis patch testing is painless and non-invasive. It is normal to experience some itching while the patches are in place and for a short while after if a reaction is present.


“I have experienced regular, chronic itchiness from my head to my toes for months. I saw PA Ivanna, and she listened to my concerns and my history of skin and allergy problems. My patch testing results came back with strong positives for multiple fragrance mixes and Nickel. This was the first time I had ever been told that I was allergic to fragrance and the different fragrance mixes. I went home and started looking at all of my products and was shocked because the fragrance is in more things than I realized. It’s been four weeks since my patch testing, and I am happy to say that I’m itch-free! “
