Title: Antibody responses to SARS-CoV-2 in COVID-19 patients: the perspective application of serological tests in clinical practice Document date: 2020_3_20
ID: dm8yl4xu_35
Snippet: On March 1, 2020, serum samples were collected from these 164 cases for antibody tests. The 16 RT-PCR confirmed cases were positive in IgG or/and IgM. Strikingly, 7 of the 148 cases who were excluded previously by negative nucleic acid results also showed positive results in IgG or/and IgM, indicating that 4.3% (7/162) of close contacts were missed by nucleic acid test. In addition, about 6.1% (10/164) of this cohort were asymptomatic infection......
