The Technology and Methodology of T.R.U.E. Test
The T.R.U.E. Test employs a thin-layer, rapid-use epicutaneous patch system to diagnose allergic contact dermatitis. This type of dermatitis occurs when the skin comes into direct contact with an allergen, triggering an immune response that leads to inflammation and skin irritation.
The T.R.U.E. Test consists of a set of patches that contain common contact allergens known to cause allergic contact dermatitis. When applied to the patient's back, these patches come into contact with the skin, allowing the allergens to penetrate the outer layer and trigger a localized immune response.
The immune response is characterized by the release of inflammatory mediators, such as histamines and cytokines, which cause redness, itching, and swelling at the site of contact. By evaluating the skin's reaction to each patch, healthcare providers can identify the specific allergens responsible for the patient's symptoms.
The T.R.U.E. Test is a convenient and reliable method for diagnosing allergic contact dermatitis. It provides valuable information about the allergens that trigger the patient's skin reactions, allowing for targeted treatment and avoidance strategies.
