Abstract

A method for applying reactive films containing solids to microporous membranes is provided wherein the membrane is firstly moistened and the reactive film containing solids is applied to the membrane while it is still moist. Membranes produced in this manner can contain reactive films having a high proportion of film openers and can be used advantageously in diagnostic elements for detecting constituents and, in particular, large hydrophobic analytes in body fluid.
