Abstract

A process is disclosed for detecting cells in a liquid sample, which includes: i) filtration of the liquid sample through a porous membrane which is suitable for retaining detectable cells, where at least one subregion of a support is configured as transparent supporting body and the membrane is arranged over its area on the transparent supporting body in such a way that detectable cells are retained on at least part of the surface of the membrane and that at least part of the sample liquid passes through the membrane, ii) application of a liquid optical medium which has essentially the same refractive index as the supporting body, and iii) optical measurement of at least a subarea of the membrane in order to detect detectable cells.
