MULTIPLEX LATERAL FLOW ASSAY FOR DIFFERENTIATING BACTERIAL INFECTIONS FROM VIRAL INFECTIONS

Abstract:

Lateral flow assay devices, systems, and methods described herein measure concentration of a plurality of analytes of interest in a sample, and can determine the precise concentration of the plurality of analytes of interest, where one or more analytes of interest are present in the sample at high concentration and where one or more analytes of interest are present at low concentration. Precise concentration of each of the plurality of analytes can be determined when a single sample is applied to a single lateral flow assay in a single application, including when a first analyte of interest is present in the single sample at one-millionth the concentration of a second analyte of interest in the single sample.
