The invention relates to a diagnostic tape unit with a test tape (12), which can be wound on a coil and consists of a transporting tape (18) and a plurality of test elements (20), which are mounted thereon. The test elements (20) have a layer of analytical reagents (34), a backing layer (36) carrying the layer of reagents (34) and a piece of adhesive tape (28), connecting the backing film (36) with the transporting tape (18). At its front side (24) facing away from the backing film (36), the layer of reagents (34) is formed so that sample substance may be applied. According to the invention, it is proposed that, in conjunction with the light-transmitting transporting tape (18), the test elements (20) in each case form an optical multilayer system for a rear, reflection photometric measurement of the reagent layer (34). |
