How Patch Testing Works

Patch testing involves applying small patches containing various allergens to the patient’s back. The patches are left in place for 48 hours and then removed to check the skin for allergic reactions. A further check is performed 48 hours later to identify any delayed reactions.

To diagnose a skin allergy, Dr. Mireku examines the patch sites and identifies the inflammation or blistering that can occur. This information is factored in with an analysis of symptoms and patient medical history, making it possible to precisely diagnose an allergy. Patch test results are an important component of delivering patient-focused allergy care that reduces the risks of severe reactions.

Contact dermatitis is caused by exposure to one of many possible allergens that trigger eczema, inflammation and other types of skin allergy reactions. The patches used during testing carry various allergens, including fragrances, detergents, ragweed, essential oils, hair dyes, preservatives, resins and metals. After a detailed consultation Dr. Mireku will discuss the appropriate treatments.

Patch testing is an accurate method of identifying the allergens that are causing a skin condition. It’s essential for learning more about skin allergies, and has been in use for over a century. Patch testing also differentiates between contact dermatitis and other allergies, and forms the basis of a comprehensive allergy treatment plan.

Common Questions About Patch Tests

Patch testing is not usually painful, though patients may experience mild discomfort or itching in the places where patches are applied. This discomfort is most likely caused by an allergic reaction to one of the substances.

Patch testing is used to identify the allergens causing allergic contact dermatitis. This skin condition is caused by direct contact with an allergen. In contrast, environmental allergies and allergies to food are usually diagnosed using skin prick or blood tests.

To prepare for a patch test, avoid using topical creams or anti-inflammatory medication on the areas where the patches will be placed. In addition, limit sun exposure for one week before the test. Your allergist will advise you of any further restrictions.
