SARS-CoV-2 antibodies titration: a reappraisal [PDF]

Annals of Translational Medicine, 2020
Taken together, the current clinical and technical evidence around SARS-CoV-2 serology would strongly persuade us that anti-SARS-CoV-2 immunoassays not only should be characterized by high analytical sensitivity and dynamic detection range, but shall also be based on quantitative assessment of a single immunoglobulin class, rather than providing ...

Profile of specific antibodies to the SARS-CoV-2

Journal of Medical Microbiology, 2021
In this work, we studied the profile of IgM and IgG antibody responses to SARS-CoV-2 in 32 patients with COVID-19 from day 1 to day 24. IgM remained measurable for a much shorter period than IgG, suggesting that IgG antibody may represent the primary immune response.
