Patch Testing

Patch testing is a painless procedure that is performed when there is a concern for allergic contact dermatitis. This form of testing involves having patches taped onto your back to detect whether you have an allergy to something that is coming into contact with your skin. Common culprits are jewelry, fragrances, latex, soaps, poison ivy or dyes. We use T.R.U.E TEST Ready-to-Use patches which contain small chambers and tape them to your back for 2 to 4 days using hypoallergenic tape. The patches contain potential causes such as fragrances, hair dye, nickel, and preservatives. After 2 to 4 days you return to the office to have the patches are removed and we examine your skin to see if a rash has occurred in response to one of the patches. We have you return for an additional visit that week to examine your skin a second time as well. You will be provided with detailed information about the allergens you react to, where they can be found and how to avoid them.

When is Patch Testing Performed?

This type of testing is performed when a patient is suspected of having a contact dermatitis which is a skin rash that is due to an allergy to something their skin is coming into contact with. This is typically a <strong>delayed reaction</strong> that does not occur immediately when the allergen is applied to the skin, therefore it can be difficult for a patient to <strong>identify the cause</strong> of their rash. During a consultation with Dr. Rajan, she can examine your skin to see if you are experiencing a contact dermatitis and whether patch testing is a good option for you.
