9. Antigen detection tests
Rapid antigen detection tests, using the same lateral flow immunochromatographic format described above, are being developed as an alternative to the real-time RT-PCR to demonstrate the presence of virus in clinical samples. Rather than detecting viral RNA, these assays use laboratory-produced anti-SARS-CoV-2 antibodies to capture and detect antigens on the surface of the virus. Various commercial manufacturers are developing and marketing antigen detection tests as a cheaper, quicker alternative to RT-PCR that can be delivered at point-of-care.
