​​Type of Patch Testing

Comprehensive patch testing helps diagnose unexplained contact dermatitis.

North American Series Patch Testing
The type of patch testing administered at Kelsey-Seybold Clinic tests a series of allergens that are most common in North America, and are chosen specific to your particular case.

If it is determined that you may have contact dermatitis, Dr. Griffin's staff will apply tiny amounts of substances that are common allergens with small patches that adhere to your skin. The most common area of testing is the back. After 72 hours, you return to our offices where we will remove the patches and examine the test results.

You will be asked to return in another 48 hours to see if there is a delayed allergic reaction to any of the substances.

If you have unexplained dermatitis and would like more information on patch testing at Kelsey-Seybold's Tanglewood Clinic, please con​tact us.
