ABSTRACT:
A chromatic test device for the performance of immuno- or chemical assays wherein a unitary planar fibrous filter body incorporates a sample application zone, a separation zone and a reaction zone and the application zone is in fluid communication with a first absorbent and the reaction zone is in fluid communication with a second absorbent to establish bilateral flow of the fluid component of the sample and of the analyte applied to the zones during the performance of an assay.
