Reactivity to IgM was also higher than that detected by using Kit B and C on Feb 17, respectively. Furthermore, IgM and IgG antibody levels were 0.92 AU/mL, 13.46 AU/mL, respectively, which was higher than that detected by using Kit D on Feb 17 (Figure 1 ). In the present study, IgG/IgM antibodies to specific proteins of SARS-CoV-2 were found in blood sample of the patient and gradually increased. Because COVID-19 is a newly emerged disease, the patient with either positive for IgM or IgG antibodies to SARS-CoV-2 should be considered as the presence of SARS-CoV-2 infection. So we believe that positive for IgM or IgG antibodies could be a marker to diagnosis of SARS-CoV-2 infection no matter the results of testing nucleic acid.	./cache/cord-275250-ilmgy7ce.txt	./txt/cord-275250-ilmgy7ce.txt
