Photographs of typical results under a fluorescent light source, and the corresponding fluorescence readouts as a colour-gradient matrix, normalized to the maximum readout value. Group E consists of COVID-19-negative results only. The horizontal line on the colour bar indicates the cut-off value. A colour-gradient matrix for the fluorescence readouts of 734 clinical samples is provided in Supplementary Fig. 4, and the corresponding numerical data in Supplementary Dataset 3.
