Abstract

See full text

In a test strip for the detection of a component in a liquid sample, the strip comprising a support layer, a microporous polymer layer and a reagent for the detection of the component to be determined, the improvement wherein the microporous polymer layer is a membrane which has an asymmetric pore structure with the narrower pores being on the side to which the sample is applied, and the support layer is macroscopically smooth. The porous membrane is produced by coagulation from solution.
