Abstract

A method for producing an analytical consumable is proposed. The analytical consumable comprises at least one carrier and at least one analytical aid connected to the carrier. At least one optically sensitive material is applied to the carrier, said material being designed to carry out at least one optically detectable alteration in the event of action of an electromagnetic radiation. In at least one coding step, at least one function information item about the analytical consumable is introduced into the optically sensitive material by means of electromagnetic radiation. The function information item is designed to enable at least one analytical instrument to use the analytical consumable correctly.
