The analytical test unit (18) includes a test element (22) having a carrier film (28), and a body fluid loadable reagent layer (32) formed at the support side (30) of the carrier film. A light transmissive support film for optical scanning of the reagent layer is positioned in the beam path of a photometric measuring unit. The carrier film is comprised of a raised surface structure (42) having a modified surface to reduce reflections in the optical path of photometric measuring unit. An independent claim is included for analytic test system for detection of analyte in bodily fluid.
