Claim 10:
11. A method for the manufacture of a multiparameter lateral flow membrane according to claim 1, comprising the steps of:
(a) providing a lateral flow membrane, comprising a microporous membrane layer for lateral flow of a liquid through the microporous membrane layer,
(b) laser-etching of the microporous membrane layer to form hydrophobic separation channels, such that two or more isomorphic flow lanes are provided in the direction of lateral flow, the two or more isomorphic flow lanes run parallel and adjacent to one another, and the two or more isomorphic flow lanes are zig-zag-shaped lanes or meander-shaped lanes,
(c) optionally processing step (b) on a membrane roll, and
(d) applying a detection zone including one or more binding agents on each of said two or more low lanes.
