Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a test strip or a biosensor for testing the concentration of an analyte in a body fluid.SOLUTION: The test strip includes a base substrate (12), a spacing layer (14) and a covering layer (16) comprising a body cover (18) and a chamber cover (20). The spacing layer includes a void portion (22) to provide a sample-receiving chamber. The base substrate carries an electrode system (26) including electrodes (28) and terminating in contact pads (32). The electrodes are defined as those portions of electrodes traces that are positioned within the sample-receiving chamber. A suitable reagent system (33) overlies the electrodes within the sample-receiving chamber. The body cover and the chamber cover overlying the spacing layer define a slot (34) therebetween, the slot defining a vent opening communicating with the sample-receiving chamber to allow air to escape the chamber as a sample fluid enters the chamber from the edge opening or fluid receiving opening.
