The present disclosure generally relates to lateral flow immunoassay systems, devices and methods, for detecting analytes in biological samples. More specifically, the present disclosure relates to synthetic thread based lateral flow immunofluorescent assay systems, devices and methods. The lateral flow immunofluorescent assay devices can comprise one or more synthetic polymer threads defining at least a sample loading zone, a detection zone comprising an immobilized capture reagent that has affinity for a predetermined analyte in the sample, and an intermediate zone disposed between the sample loading zone and the detection zone, the intermediate zone comprising a fluorescent detection reagent for use in binding to a predetermined analyte in the sample to form a fluorescently labelled analyte, wherein the fluorescent detection reagent comprises fluorescently labelled microparticles that are associated, linked or coordinated to an analyte binding reagent that has affinity for a predetermined analyte in the sample, and wherein the one or more synthetic polymer threads are capable of carrying a fluid sample by capillary action from at least the sample loading zone to the detection zone.
