    Snippet: Because swab samples had limited sensitivity for initial diagnosis of cases of SARS 13,14 , we analyzed the first paired swab and sputum samples taken on the same occasion from seven patients ( Table 1) . All samples were taken between 2 and 4 days post-onset. In two cases, swab samples had clearly higher virus concentrations than sputum samples, as indicated by a difference greater than 3 in threshold cycle (Ct) value. The opposite was true in t.....
    Document: Because swab samples had limited sensitivity for initial diagnosis of cases of SARS 13,14 , we analyzed the first paired swab and sputum samples taken on the same occasion from seven patients ( Table 1) . All samples were taken between 2 and 4 days post-onset. In two cases, swab samples had clearly higher virus concentrations than sputum samples, as indicated by a difference greater than 3 in threshold cycle (Ct) value. The opposite was true in two others cases, while the other 5 cases had similar concentrations in both sample types.
