To verify its applicability, the viral RNA was tested with the six kits provided by Shanghai Liferiver Bio-tech Co., Ltd, Wuhan Huada Bio-tech Co., Ltd, Shanghai GeneoDx Biotech Co., Ltd, DAAN Gene Co., Ltd of Sun Yat-sen University, Sansure Biotech Inc., and Shanghai BioGerm Medical Co., Ltd. The different target genes ( Table 1 ) produced typical S-shaped amplification curves, indicating that the RNA could be used in the six kits to evaluate their LoDs. The viral RNA concentration was determined with RT-droplet digital PCR (RT-ddPCR), which allows the absolute quantification of viral RNA by counting single molecules, without reference to an external standard curve.
