FDA clearance with CLIA waiver for Point-of-Care settings
For use with SOFIA 2 Analyzer
SOFIA 2 SARS Antigen+ Fluorescent Immunoassay (FIA) is the first FDA-cleared, 10-minute rapid antigen test for COVID-19.*
The next generation of COVID-19 rapid testing, SOFIA 2 SARS Antigen+ Fluorescent Immunoassay (FIA), uses advanced immunofluorescence-based lateral flow technology in a sandwich design for the rapid, qualitative detection of SARS-CoV-2 nucleocapsid protein antigens directly in anterior nasal swab specimens. The SOFIA 2 SARS Antigen+ FIA, with the SOFIA 2 analyzer, provides automated results in 10 minutes, allowing for COVID-19 testing of symptomatic patients when testing is started within 6 days of symptom onset.
This test is intended for use as an aid in the diagnosis of SARS-CoV-2 infections in symptomatic individuals when either: tested at least twice over three days with at least 48 hours between tests; or when tested once, and negative by the SOFIA 2 SARS Antigen+ FIA and followed up with a molecular test.
SOFIA 2 SARS Antigen+ FIA is now available for healthcare professionals to purchase. Contact your QuidelOrtho Account manager for more details.
