Comparison of the results from the CLEIA antigen test and the RT-qPCR test for SARS-CoV-2.

	RT-qPCR+; (%)	RT-qPCR-; (%)	Total; (%)
CLEIA + (≥1.34 pg/mL)	205 (91.9%)	18 (8.1%)	223 (24.5%)
CLEIA - (<1.34 pg/mL)	11 (1.6%)	677 (98.4%)	688 (75.5%)
Total	216 (23.7%)	695 (76.3%)	911

RT-qPCR: Real-time Reverse transcription-Polymerase Chain Reaction; CLEIA: chemiluminescence enzyme immunoassay.
