Patch Testing

Experiencing Chronic Rashes? Get Diagnosed with Patch Testing

Chronic rashes due to allergic contact dermatitis can have a variety of causes and not knowing what can trigger these flare ups can be frustrating. Thankfully, Patch Testing at Knott Street Dermatology can determine the causes, allowing patients to make the necessary adjustments to prevent these rashes from occurring in the future.

Patch testing differs from blood allergy testing, it involves applying pads that contain suspected allergenic substances from the North American Contact Dermatitis Society’s core allergen list to the entire surface of the back. These common chemicals can be found in jewelry, skin care products, soaps, cosmetics, fragrances, and clothing fabric.

Patients are first assessed by a provider to determine if patch testing is appropriate for the type of rash, and then insurance authorization is obtained to determine out-of-pocket expenses for the testing.

Once allergenic substances causing the allergic contact dermatitis flare ups are determined, patients will finally be able to prevent future breakouts!
