Abstract

Medical test strip comprises a substrate (1) with a pointed projection (11) on one side, on which is bound a central layer with an aperture which faces the projection, forming a sample chamber, and a cover strip which is fitted over the middle layer which also has a pointed projection (31'), the two projections forming an inlet leading to the chamber.
