Quantitative non-instrumental immunoassay and device using coloured particles

A quantitative chemical method of analysis for determining concentrations of one or several analytes in a sample, characterized in that a sample containing the analyte or analytes is mixed with a reagent contained in a container, wherein the reagent contains signal-providing substance(s), thus providing a mixture which is subsequently absorbed by a fluid-transmitting material contained in a fluid-transmitting device after coupling of the container to the fluid-transmitting device, and simultaneously or afterwards bringing the fluid-transmitting device in contact with a fluid-receiving device containing a fluid-receiving material which includes immobilized reagents with specific binding capacity for the analyte or analytes, or immobilized analyte molecules or analogues or derivates or fragments thereof, wherein the mixture is transported out in the porous fluid-receiving material in the said other fluid-receiving device and create a pattern wherein the pattern or area of the pattern or area of the pattern elements are utilized as a measure of the concentration of analyte or analytes in the sample.
