The lateral flow immunofluorescent assay is designed to be used with the Sofia 2 fluorescent immunoassay analyser for the qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 in direct anterior nasal swab specimens.

Specimens are collected within six days of symptom onset from individuals with signs and symptoms of upper respiratory infection.

When tested at least twice over three days, with a gap of at least 48 hours between tests, the Sofia 2 test will help diagnose SARS-CoV-2 infections in individuals with symptoms.
