Abstract

Test carrier analysis system for analyzing a constituent of a body fluid, consisting of test carriers (2), code carriers (3) and an evaluation device (4). The test layers (5) of the test carrier (2) contain reagents whose reaction with the sample leads to a color change characteristic of the analysis in a detection layer. The code carriers (3) contain in machine-readable form an evaluation code with an evaluation curve required for the evaluation of the test carriers. The evaluation device (4) comprises a measuring device, a code reading device and evaluation electronics. Possible operating errors are eliminated, almost without additional expenditure, by the fact that single code reader containing two reading units offset relative to one another both laterally and in the reading direction is positioned on a common insertion path (28) both for the test carriers (2) and for the code carriers (3), the test carriers (2) possess a batch-specific identification code in the form of continuous strips, the evaluation code on the code carriers (3) is a two-track code and contains a batch identification, and the evaluation device (4) comprises a comparison unit for checking the correlation of the batch of the respective test carrier (2) to be evaluated with the stored evaluation information.
