The invention relates to a test device for examining, in particular, a biological sample liquid with a composite body (10) formed from several flat material layers (12, 18, 30) and a sample channel (20) arranged in the composite body (10) for transporting the sample liquid from a feed point (22 ) to a measuring point (24). According to the invention, it is proposed that the composite body (10) have a plurality of transport layers (18) arranged in stack form between carrier layers (12), each for receiving a sample channel (20). |
