A two-step capillary flow immunoassay is provided where firstly sample with biotinylated antibody specific to the analyte is applied to a wicking strip to flow to encounter an immobilised immunoreactant which is either antibody specific to the analyte or is the analyte, and optionally to flow to an immobilised control antibody, and secondly gold-labelled antibody specific to biotin is applied.
