Fig. 2: Sensitivity of the HC-FIA assay.

From: Rapid lateral flow immunoassay for the fluorescence detection of SARS-CoV-2 RNA

Fig. 2

The vertical axes show the fluorescence-intensity ratio (T/C) of the test signal (T) and the control signal (C). For each concentration, 20 tests were conducted in parallel. The LOD was determined as the concentration at which the positive rate was greater or equal to 95%. a, T/C ratios for serially diluted pseudovirus samples positive for the N, E and ORF1ab regions of SARS-CoV-2. b, T/C ratios for serially diluted throat swab samples from three critically ill patients. Data are mean ± s.d.
