POINT-OF-CARE BIOMARKER ASSAY APPARATUS ARRANGED FOR MEASURING A PRESENCE OR CONCENTRATION OF A BIOMARKER IN A SAMPLE

摘要

Point-of-care biomarker assay apparatus arranged for measuring a presence or concentration of a biomarker in a sample, said biomarker assay apparatus comprising cartridge receiving means arranged for receiving at least one cartridge having multiple chambers designed for receiving a plurality of liquid media comprising said sample, labelled binding reagent, magnetic beads reagent and wash buffer, a sample distribution unit arranged for processing pipetting steps with said chambers, thereby providing a liquid reactant mixture in one or more of said chambers, a magnetic coil assembly arranged for applying a magnetic field to said liquid reactant mixture for separating biomarkers bound to said magnetic beads and said labelled binding reagent, from said reactant mixture, a photo detector or assembly arranged for measuring said presence or concentration of said labelled binding reagent, a control unit arranged for controlling said processing pipetting steps with said chambers, and for controlling said sample distribution unit along said chambers according to a test protocol, wherein said test protocol comprises an order of subsequent processing steps performed in said plurality of chambers to be processed by said sample distribution unit, said processing steps comprising one or more processing pipetting steps by the sample distribution unit and one or more processing incubation steps of the reaction mixture within any of the chambers wherein the control unit being programmed for performing multiple, distinct test protocols.
