Allergic contact dermatitis is caused when skin comes in contact with substances that cause immune mediated reactions on the skin. Classically, contact with allergens will cause an itching red blistering skin eruption. At The Dermatology Group our physicians will attempt to identify the causative allergen. If the allergen is not identified through history and physical exam then comprehensive patch testing can be undertaken.
Patch testing is a safe and effective way to diagnose chronic allergies. Samples of common allergens are taped to the patient’s back and removed in two days. Allergic reactions present as red swollen patches. Based on the allergen our physicians can recommend products which must be avoided as well as products that are free of the offending agent.
At The Dermatology Group the North American Standard 45 allergen panel is routinely applied to affected patients in order to identify possible allergens. This test is a comprehensive collection of commonly used substances found in daily life that cause the majority of skin allergies in North America.
