Abstract

A test tape cassette is disclosed that includes a cassette housing and an analytical test tape. The test tape includes a plurality of analytical test elements, a spreading fabric for applying a body fluid, and an underlying reagent layer for detecting an analyte in the body fluid. The cassette housing has an application tip that has a guide path extending longitudinally to the test tape in an arched-shape and is uncurved at right angles thereto for supporting the test tape in a kink-free manner. The guide path has an apex area with a central opening that delimits a measuring window for an optical measurement on the test elements.
