Abstract
An assay device () for determining the presence and/or amount of an analyte present or potentially present in a liquid sample comprises: (i) a capillary tube () having an upstream region () into which the sample to be assayed is introduced for transfer by capillary action along the capillary tube to a downstream region thereof; (ii) a collection of first binding partners () immobilized within the capillary tube (), said first binding partners () being capable of specifically binding to the analyte; (iii) a collection of second binding partners () displaceabley bound to a fraction of said first binding partners () whereby there are free first binding partners () immobilized within the capillary tube, said second binding partners () having a label and being displaceable from the first binding partners () by the analyte to be detected; and (iv) a detection region () for sample that has transferred to said downstream region of said capillary tube, said detection region being adapted to generate a detectable signal from the label on displaced second binding partners () that have transferred to the downstream region.
