Diagnostic evaluation reports SARS-CoV-2 antigen detection performance across rapid lateral flow devices in tested cohorts, highlighting shifts in sensitivity.
We investigated if performing two lateral flow device (LFD) tests, LFD2 immediately after LFD1, could improve diagnostic sensitivity or specificity for detecting severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) antigen.
