Abstract

A system for determining an analyte in a body fluid includes a magazine comprising two partial magazines, one including chambers containing analysis elements having a sample contact zone and a reagent system containing a reagent, whose reaction with the body fluid results in a change of a variable, and another including chambers containing puncturing elements having a tip having a capillary channel, which forms a fluid connection between the tip and a sample transfer zone of the puncturing element. The system may also include an analysis instrument having a puncturing drive for driving a puncturing element on a movement path, a mounting for receiving the magazine such that one chamber of the magazine at a time is located in a functional position, in which a puncturing element in the chamber can be moved by the puncturing drive, and a measuring and evaluation apparatus for measuring the change of the variable.
