RT-qPCR tests presented a high specificity with a low probability of false positive; however, sensitivity relies on different factors as specimen site, method of collection, viral load and time from the onset of symptoms [3, 7] . Detection rate of IgM, IgG and IgM/IgG antibodies against SARS-CoV-2 with the three ICT strip assays in positive and negative RT-PCR patients along three periods of time since the onset of symptoms is shown in Table 3 . Detection rates of total antibodies (IgM/IgG) obtained with Sienna® and Wondfo® by the two groups of patients along the three stages since the symptoms onset are collected in Table 4 . In this study, we have investigated the diagnostic value of detection of SARS-CoV-2 IgM and IgG antibodies in different stages of the disease, using three ICT strip assays, in comparison with RT-qPCR.	./cache/cord-336909-nnxa5ant.txt	./txt/cord-336909-nnxa5ant.txt
