Contact Dermatitis

Contact dermatitis affects approximately 15% to 20% of the general population worldwide, making it one of the most common skin conditions. 

Contact dermatitis is a common skin condition caused by direct exposure to irritants or allergens. It presents as red, itchy, and scaly patches, often with well-defined borders, on areas like the hands, face, and neck.

There are two types: irritant contact dermatitis, triggered by substances like soaps, detergents, or chemicals, and allergic contact dermatitis, which is a delayed immune reaction to allergens such as poison ivy, nickel, latex, or fragrances. Symptoms may include burning, itching, dryness, or even blisters.

Accurate diagnosis and allergen identification, often through patch testing, are key to effective treatment and long-term relief.

Patch Testing

Patch testing is a specialized diagnostic tool used to identify allergic contact dermatitis, skin reactions caused by allergens like fragrances, metals, preservatives, and other substances. Unlike prick testing for immediate allergies, patch testing detects delayed allergic responses by applying small amounts of allergens to the skin and monitoring reactions over 48–96 hours. This test helps pinpoint the exact cause of contact dermatitis, chronic rashes or eczema-like symptoms, allowing for personalized treatment and long-term relief. 

Asthma & Allergy Specialists offers comprehensive patch testing to help patients manage and prevent future flare-ups.
