Patch testing is performed when patients have an allergic skin condition called contact dermatitis. Contact dermatitis occurs when a patient becomes allergic to something which is coming in contact with their skin. Patients with contact dermatitis have recurrent or chronic episodes of itchy skin rashes. Patients can often become allergic to fragrances, dyes, preservatives or other chemicals in their personal care products. Patch testing is performed to help determine which contact allergens the patient is allergic to.
Our patch testing is based off the North American Contact Dermatitis Group series of allergens consisting of the most common contact allergens. Hypoallergenic patches containing individual allergens are applied to the patient’s back and the patches should be kept dry while in place. The patient then returns 2 days later to have the patches removed and read. There will be an additional appointment to have the patch testing results read 4 days after they were placed. The patient will be scheduled to meet with the doctor to review the results of the testing. We will teach you how to avoid your particular contact allergens, how to look for those allergens in your personal care products, and will give you lists of products which would be safe for you to use based off your specific test results.
