The Sofia 2 Flu + SARS Antigen Fluorescent Immunoassay (FIA) uses advanced immunofluorescence-based lateral flow technology in a sandwich design for qualitative detection of nucleocapsid protein from influenza A and influenza B, and SARS-CoV-2. The Sofia 2 Flu + SARS Antigen FIA with the Sofia 2 analyzer provides automated and objective results in 15 minutes, allowing for testing of patients suspected of influenza A, influenza B, and COVID-19/2019-nCoV at the Point of Care.
Sofia 2 is a small bench top analyzer that uses advanced fluorescence detection with an ultraviolet LED energy source. Sofia 2 collects hundreds of data points on the test strip contained inside of a Sofia FIA Test Cassette. Sofia 2 uses proprietary algorithms to analyze the data, interpret the signals and determine the results automatically to give you an objective result you can rely on.
