Sumario:Seroconversion panels are an important tool for investigating antibody responses and developing serological assays. A seroconversion panel was generated from a single SARS-CoV-2 positive plasma donor over 87 days. This seroconversion panel was tested against 6 SARS-CoV-2 antibody tests (IgG, IgM, and total Ig). All test kits utilized recombinant antigens that are specific to SARS-CoV-2. The seroconversion panel showed IgG responses for SARS-CoV-2 after day 50. IgM levels peaked on day 50 (prior to IgG) and declined in subsequent samples. This seroconversion panel is a useful tool for validation of SARS-CoV-2 antibody assays.
