ABSTRACT:
An apparatus is provided for the detection and semi-quantitative measurement of analytes. The assay results are visualized by the formation on a filter of a colored annular or circular spot, the diameter of the spot being related to the concentration of the analyte of interest. The filter on which the assay results are visualized is divided into multiple regions by strips of non-porous tape crossing the filter surface. The invention also includes a component for diluting sample to a suitable concentration for analysis, and dispensing the diluted sample onto the test filter.
