Thus, serological testing, especially to detect NAbs, is essential in determining the onset of the serological immune response, evaluating the potential capacity of the host body for viral clearance, and identifying donors for passive antibody therapy trials. 12, 13 However, the dynamics and roles of SARS-CoV-2-specific NAbs and their correlation with antibody responses have not been explored in COVID-19 patients more than two months after symptom onset. Furthermore, to determine if there was a statistical correlation between NAb levels and virus-specific IgG levels in COVID-19 patients, serum samples were grouped by time (weeks) after symptom onset. In summary, we determined the dynamics of NAb titers within 3 months after symptom onset in 30 SARS-CoV-2-infected patients and found a positive correlation between NAb titers and IgG antibodies. ./cache/cord-279550-7u2hksxm.txt ./txt/cord-279550-7u2hksxm.txt
