Allergy Patch Testing

Allergy patch testing is a diagnostic method used to identify allergic contact dermatitis, a delayed hypersensitivity reaction that occurs when the skin comes into contact with specific allergens. Unlike immediate allergic reactions seen in conditions like hay fever or food allergies, contact dermatitis develops slowly over time upon exposure to certain substances.

Here's an overview of allergy patch testing:


During patch testing, a series of small patches containing potential allergens (substances that commonly cause skin reactions) are applied to the skin, usually on the back. These patches remain in place for around 48 hours. The patches are then removed, and the skin is examined for any signs of allergic reactions.

Identification of Allergens:

The allergens used in patch testing can include various substances like metals (nickel, cobalt), fragrances, preservatives, latex, certain medications, and other chemicals commonly found in everyday products. The test aims to identify specific substances triggering allergic reactions in an individual.

Reading and Interpretation:

After the patches are removed, our board-certified allergist examines the skin to look for any reactions. Reactions may appear as redness, swelling, blisters, or a rash at the patch sites. The presence and severity of these reactions help identify the substances causing allergic contact dermatitis.


Patch testing is essential in diagnosing allergic contact dermatitis, especially when a person experiences chronic or recurring skin issues that don’t respond to typical treatments. It helps pinpoint the specific allergens causing the skin reaction, enabling healthcare providers to recommend avoidance strategies and tailored treatment plans.


Patients undergoing patch testing are usually advised to avoid excessive sun exposure on their backs before and during the test to ensure accurate results. They may also be instructed to refrain from using certain topical medications or skin care products that could interfere with the test.


After patch testing, the allergist discusses the results with the patient, identifies the allergens causing reactions, and recommends strategies to avoid these substances. He may also suggest treatments or lifestyle adjustments to manage allergic contact dermatitis.
