Abstract: Chromatographic analysis devices (1) are described for the detection of blood parameters, consisting of cell components of cells circulating in blood of human or animal origin, or of plasma components, in a sample of a bodily fluid containing such cells, comprising a strip-shaped chromatographic medium (3) having a sample application zone (4), a suction zone (5), and at least one detection zone (6, 7) wherein application zone, suction zone and detection zone are mutually separated from each other by at least one separation zone (8a, 8b, 8c), which is (are) each provided with a material inhibiting lysis of the circulation cells. Test kits for performing such analysis are described as well.
