Abstract
Method for applying a coating of allergen on a steel tip of an instrument which is to be employed for in vivo allergy diagnostication and which has stop means adjacent to the steel tip so that solely said tip can penetrate the skin. The characteristic feature of said method is that the steel tip plus those portions of the stop means that lie in the immediate proximity of said tip are acid-pickled and then coated with allergen, to thus cause an active amount of allergen to adhere to said tip.
