Abstract: An analyte reading system which includes a reader unit for rapidly detecting and evaluating the outcome of an assay to measure the presence of analytes in a sample. Quantitative and qualitative measurements of analyte concentration in a sample may be rapidly obtained using the reader device with algorithms which ascertain the nature of the assay and perform a comparison against a calibration sample. The reader device scans preset areas of an assay device in order to provide focal points for the reader device and evaluate the volume of the test sample in the assay device. The reading portion of the assay slide has at least one test dot for detecting the presence of the analyte and the signal intensity of the labelled analyte, and processes the detected signal using an algorithm which provides an accurate output measurement indicating the quantity of the analyte in the test sample.

Abstract: Assay devices are disclosed comprising a base defining a cavity and an insert received in the cavity. The cavity has major surface and at least one sidewall, preferably surrounding the major surface. The insert comprises a first surface with a portion opposing the major surface of the cavity. A space is provided between the portion of the first surface and the major surface for the receipt of a fluid sample. The space has an entrance defined by the first surface of the insert and the major surface. The insert also comprises a second surface opposing the first surface and having an input portion for the application of a fluid sample. The input portion is in fluid communication with the entrance to the space, such that a fluid sample applied to the input portion passes to the entrance to the space and into the space. At least one or more passages is preferably defined through the insert, for passage of the fluid sample through the insert, to the entrance to the space.
