Allergic & Contact Dermatology

Allergic contact dermatitis is a type of skin rash caused by substances (allergens) coming into contact with the skin and stimulating an immunologic response. These substances can be found in many common products, such as lotions, soaps, gloves, metal products and hair dyes. Sometimes these substances are encountered in a work setting. 

Patch testing is a special, non-invasive technique to identify the specific chemicals that can cause itchy or painful skin rashes for a patient. Identifying and avoiding these triggers can sometimes cure rashes that patients struggle with for years. During patch testing, a small amount of various substances which you may be allergic to will be applied to your back and secured in place with an adhesive. Testing does not involve skin pricks, blood draws or injections. If an allergen is uncovered, we will provide you with information about how to avoid this allergen moving forwards. 

Our clinic offers testing to a wide array of allergens, including those that can be encountered in an occupational setting (Level 4). Testing is guided by every patient's unique history of exposures and exam. Referrals from dermatologists are needed for scheduling.
