Abstract

The present invention relates to systems and methods that utilize a combination of immunoassay and magnetic immunoassay techniques to detect an analyte within an extended range of specified concentrations. In particular, a device includes a housing, a heterogeneous surface capture immunosensor within the housing and configured to generate a first signal indicative of the concentration of the analyte in an upper concentration range, and a homogeneous magnetic bead capture immunosensor within the housing and configured to generate a second signal indicative of the concentration of the analyte in a lower concentration range.
