[Justification for introducing specific patch test series in the diagnosis of contact allergies].

In contact allergy diagnostic procedures, beside the epicutaneous PATCH testing with commercial products, the authors form a standard as well as a certain number of specific epicutaneus allergen series, in order to prove the relationship between results in two different kinds of investigations, and the justification of testing with certain components of a complex product, in which the causative agent is often presented in a concentration which is lesser than the concentration needed for producing a positive PATCH test. The investigation was done including 158 patients with clinically evident contact dermatitis. TROLABR Hermal-Chemie Kurt Herrmann standard allergens were put in one standard and certain specific series such as: oil and petroleum derivatives and cutting fluids, detergents and soaps, leather, textile fabrics, glues, plastics, protective agents in agriculture, the dentist's battery, cosmetics, hair dressings and hair dyes. Allergic contact sensitivity was detected in 82.2%; in the textile battery (23.01%), in rubber, plastics and glues (15.49%), in cosmetics (12.83%), in oils, petrol derivatives and cutting fluids (12.83%). According to the results in two different kinds of testing and the statistical findings, the relationship between the two variables was estimated with a statistical significance on the level of 0.01.
