Abstract:
An assay for determining the presence or concentration of an analyte in a fluid test sample which comprises:a) providing an immunochromatographic test strip having a non-porous receiving member of a hydrophobic material in direct fluid communication with a reagent region of an absorbant material through which the fluid test sample and reagents carried therein can flow by capillarity and which reagent region contains a detection site for detecting the presence or concentration of the analyte,b) applying the fluid test sample to the receiving member, so that a portion of the fluid test sample is in direct contact with the absorbant material of the reagent region of the immunochromatographic test strip, anddetermining the presence or concentration of the analyte in the fluid test sample by correlating a detectable response in the reagent region with such presence or concentration.
