    Snippet: We analyzed the detectability of RNA test and antibody assays according to the time course since illness onset in the cohort. As the results shown in Figure 2 and Table 2, in the early phase of illness within 7-day since onset, the RNA test had the highest sensitivity of 66.7%, whereas the antibody assays only presented a positive rate of 38.3%. However, the sensitivity of Ab overtook that of RNA test since day 8 after onset and reached over 90% .....

However, the sensitivity of Ab overtook that of RNA test since day 8 after onset and reached over 90% across day 12 after onset ( Figure 2 ). In samples from patients during day 8-14 after onset, the sensitivities of Ab (89.6%), IgM (73.3%) and IgG All rights reserved.
