An analysis test strip and a process for the production of analysis test strips with a longitudinal carrier upon which is fixed at least one test field. The test field material is 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 onto a parallel-running substantially wider band of test strip carrier material. The band as a whole is cut up transversely to its longitudinal direction into a plurality of test strips. Prior to the cutting up, a bar code is applied to the carrier band running parallel to the edges thereof of such high information density that it is suitable 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.
A test strip for the analysis of components of a liquid, comprising:
The test strip according to claim 11, wherein the test field region is located near one end of the elongated carrier and the handling region is located near the other end of the elongated carrier and the bar code is disposed on the other surface of the test strip and between the test field region and the handling region.
The test strip according to claim 11, wherein the bar code includes at least 50 bits of information, includes essentially two widths of code bars and the width of the smaller kind is not more than 200 .mu.m.
An analysis test strip having an elongated carrier with at least one test field fixed thereon, produced by:
