  • Patent number: 4592893
    Abstract: 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.
    Type: Grant
