ABSTRACT The present invention provides a process for the production of an analysis test strip with a longitudinal carrier upon which is fixed at least one test field, the test field material being produced batchwise in an amount sufficient for a plurality of test strips, and thereafter, in a chronologically separate working step, is continuously fixed in the form of at least one band on to a parallel-running substantially wider band of test strip carrier material in a running through process and finally the band as a whole is divided transversely to its longitudinal direction into a plurality of test strips, whereon on to the test strip carrier band, before the dividing, there is-applied a-bar code, running parallel to the edges of the test strip carrier band, of such high information density that it is suit- able as a store of batch-specific information necessary for the quantitative evaluation of the reaction which has previously been obtained by investigation of the test field material of one batch. The present invention also provides test strips for the analysis of components of a liquid, especially of a human body fluid, comprising a longitudinal carrier with a front end and a rear end; whereby, near to the front end, there is provided at least one analysis test field and, near the rear end, there is provided a handling region in order to facilitate moistening of the test strip with a liquid to be analysed and con- veyance thereof to evaluation means and also comprising a mechanically-readable coding in the form of bars running substantially transversely to the test strip, wherein the coding is constructed as a bar code of such high information density that it is suitable as a store of batch-specific information necessary for the quantitative evaluation of the reaction.
