What is Patch Testing?

If a red itchy rash has ever appeared after trying a new perfume or wearing latex gloves, it may have been caused by an allergic contact dermatitis--a fancy term for an allergic reaction on the skin caused by something in direct contact with the skin. Products or chemicals that cause allergic reactions are called contact allergens and are exactly what they sound like: an allergic reaction develops whenever it contacts the skin. It can be hard to determine which chemicals, products, or daily household items may be causing a rash. Even a small ingredient change in a detergent can trigger a reaction. To circumvent trial and error, and avoid getting more rashes, patch testing is helpful for determining common contact allergens.

In just one week, a tailored patch testing sequence can be developed, implemented, and reviewed. But, how does it work? What does a patch testing panel look like? In patch testing, small “stickers” with common allergen substances are uniformly placed on the back. After a few days, the patches are removed and specific markers are identified at each spot to determine if the test is positive or negative for an allergen. A positive result means the respective substance causes an allergic reaction and is an allergen, and a negative response means indicates the substance is does not.

To get started, patients interested in patch testing complete initial intake forms before the first visit with Dermatology Certified Nurse Practitioner Liz Schuringa, ARNP. Liz will review the procedure and any personal products (even ones used on occasion). At a separate visit, the patches will be applied and left on for 2 days. The patches are then removed at the third visit and the spots are observed after 3 days for any positive or negative result. This last visit consists of going over results and determining which products are allergens and which ones are not.

Most insurance companies cover patch testing, but may need confirmation to be sure. Insurance copays, are typically only required at the 1st and 4th visits. For scheduling, questions, or concerns please call the office at (425) 753-2918.

Do You Use Protection?

Did you know UV exposure is the most preventable risk factor for skin cancer? The American Academy of Dermatology (AAD) recommends taking many precautions when going out in the sun. It’s important to minimize sun exposure and maximize protection. Enjoy a play on words in this video by the AAD


  • Seek shade during times of peak sun rays

  • Wear protective clothing like hats and sunglasses. Pro-tip from Dermatology Arts: Use SPF shirts and shorts for water activities (for example. rash guards / swim shirts have a UPF / SPF equivalent)

  • Apply minimum SPF 30, broad spectrum, and water resistant sunscreen

  • Reapply sunscreen every hour on the hour when outside

Rashes & Skin Allergy Testing

If you have ever experienced a red, itchy, or dry patch on your skin, you may have had eczema or another form of dermatitis. Dermatitis is a wide-range term for “inflammation of the skin.” Whereas some disorders that fall in this category can be readily diagnosed and treated, others are more complex and require additional tests.

Eczema is a type of rash that falls under the dermatitis category, and is often interchangeable with the diagnosis “atopic dermatitis.” Symptoms of eczema can be correlated with other medical conditions to form the “atopic triad” including eczema, asthma, and allergies. However, if a rash is unresponsive to initial treatments for eczema, allergy patch testing may be considered to determine if symptoms are linked to a specific chemical or personal care product.

At Bellevue’s Dermatology Arts, we create personal regimens to effectively treat most medical skin conditions including eczema and dermatitis. Our office’s allergy patch testing services are lead by Dermatology Certified Nurse Practitioner Liz Schuringa, ARNP. Please click or call (425) 753-2918 to schedule an appointment.
