Abstract
Methods and devices are provided for carrying out assays with minimal technical training where quantitative visual determinations may be made. The devices provide for a flow-path where a sample receiving element is moved from a sample receiving position to a position where it serves to bridge a transport element and a measurement element, so that the sample may be transported from the sample element to the measurement region. Labelled conjugates are provided which migrate a distance into the measurement region related to the amount of analyte in the sample.
