Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the strain of coronavirus that causes coronavirus disease 2019 (COVID-19), the respiratory illness responsible for the COVID-19 pandemic. Antibodies produced from an immune response against SARS-CoV-2 infection are used to analyze prior exposure to the virus. The present invention provides methods for detecting antibodies in response to SARS-CoV-2 infection in a single multiplex immunoassay.

Abstract: The present invention provides a microporous membrane for detecting at least one target analyte in a sample. The membrane includes an array that comprises at least one capture element and at least one control element printed on the membrane surface, at least one capture element corresponding to and being able to bind a target analyte, the plurality of control elements, when present including: i) at least one fiduciary marker, ii) at least one negative control to monitor background signal, iii) at least one negative control to monitor assay specificity, iv) at least one positive colorimetric control, and v) at least one positive control to monitor assay performance or any combination thereof.
