title: The Allergen Bank: a source of extra contact allergens for the dermatologist in practice.
abstract: The Allergen Bank was established to give dermatologists easy access to special test materials in order to make early diagnoses of special cases of allergic contact dermatitis. The Allergen Bank comprises a computer system to register several hundred contact allergens in appropriate patch test concentrations available at the allergy laboratory and the patch test results. At the request of dermatologists in practice for Allergen Bank may supply special contact allergens for aimed patch testing of contact dermatitis patients. The organization of the Allergen Bank and the procedure of its use are described. During its first 23 months 28 dermatologists asked for 2,209 allergen samples for testing of 386 patients, an average of 6 allergens per patient and 14 patients per dermatologist. A total number of 164 positive reactions have been registered, and 440 of the 540 allergens have been in use. One third of the positive reactions were caused by the 16 most frequently ordered allergens, which amounted to 340 allergen samples. The allergens included plant chemicals, acrylates, animal feed additives, fragrance chemicals and preservatives. Selected allergens were investigated for stability during handling and shipping under varying conditions relevant to the function of the Allergen Bank. The possible inhomogeneity of petrolatum based allergen preparations is discussed in relation to diagnostic patch testing.
