Abstract:
PCT No. PCT/DE92/00154 Sec. 371 Date Jul. 6, 1993 Sec. 102(e) Date Jul. 6, 1993 PCT Filed Feb. 26, 1992 PCT Pub. No. WO92/15879 PCT Pub. Date Sep. 17, 1992.Test carrier for the determination of an analyte from whole blood. Within a test field, it contains a reagent system. The test field has a sample application side to which the blood sample is fed, and a detection side on which, as a result of the analysis reaction, an optically detectable change occurs. It is designed so that the red blood corpuscles cannot gain access from the sample application side to the detection side, and it contains pigment particles for optical blockage of the red blood pigment. Reliable separation in combination with simple manufacture is achieved in that the test field (5) has a combined blood pigment separation and detection layer (1) which, in a single, very thin homogeneous layer, fulfils the functions of separation of the red blood corpuscles and optical detection. It is formed from a dispersion or an emulsion of a polymeric film former which, in homogeneous distribution, contains the pigment, the polymeric film former, the color formation reagent of the reagent system and a swelling agent.
