    Snippet: Sample collection Approximate 5 ml fasting blood samples were drawn from all the enrolled participants and collected into serum separation hose and subsequently centrifuged at 2500 g for 10 min. The serum samples were used to detect .SARS-CoV-2 IgG/IgM antibodies. Corresponding nasal and pharyngeal swab specimens were also collected for SARS-CoV-2 RT-PCR.

    Document: Sample collection Approximate 5 ml fasting blood samples were drawn from all the enrolled participants and collected into serum separation hose and subsequently centrifuged at 2500 g for 10 min. The serum samples were used to detect .SARS-CoV-2 IgG/IgM antibodies. Corresponding nasal and pharyngeal swab specimens were also collected for SARS-CoV-2 RT-PCR. Data analysis SPSS 20.0 was used for statistical analysis All tests were bilateral, and p less than 0.05 was considered statistically significant. Chi-square test or Fisher exact probability test was used to compare count data. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Kappa efficiency were calculated.
