Patch Testing

A picture of a dermatology patient in portland Oregon undergoing a patch test up close for demonstration.Allergic contact dermatitis can be the underlying cause for many chronic rashes. At Knott Street Dermatology in NE Portland, OR and Milwaukie, OR, we offer patch testing, which differs from the "pin prick" testing that most people are familiar with for identifying environmental or food allergies. Our technique involves application of patches to the entire back containing products/chemicals suspected to be the cause of your dermatitis. The patches contain substances from the North American Contact Dermatitis Society's core allergen list and can be found in jewelry, skin care products, soaps, cosmetics, fragrances, and clothing. Patients are first assessed by one of our providers to determine if patch testing is appropriate, and then insurance authorization is obtained to determine out-of-pocket expenses for the testing.

Should your provider indicate patch testing for your condition, please click on the link for an informational packet describing what the process entails.

If you have any questions about patch testing, please contact us at our NE Portland, OR or Milwaukie, OR offices.

For your convenience, in addition to our main office in NE Portland, we also provide a second satellite location at The Providence Milwaukie Healing Place building on the campus of the hospital where we see patients throughout the week.
