Snippet: Background: Seroconversion panels (SCP) are an important tool for investigating antibody responses and developing serological assays. A SCP was generated from a single SARS-CoV-2 positive plasma donor over 87 days. Methods: This SCP was tested against five SARS-CoV-2 antibody tests (IgG, IgM and total Ig). All test kits utilized recombinant antigens that are specific to SARS-CoV-2. Results: The SCP showed IgG responses for SARS-CoV-2 after day 50. IgM levels peaked on day 50 (prior to IgG) and d

All test kits utilized recombinant antigens that are specific to SARS-CoV-2. Results: The SCP showed IgG responses for SARS-CoV-2 after day 50. IgM levels peaked on day 50 (prior to IgG) and declined in subsequent samples. Conclusion: This SCP is a useful tool for validation of SARS-CoV-2 antibody assays.
