    Variant Assay:

    Article Title: Comparing Results of Five SARS-CoV-2 Antibody Assays Before and After the First Dose of ChAdOx1 nCoV-19 Vaccine among Health Care Workers
    Article Snippet: The SD Biosensor V2 assay is designed to detect antibodies to the South Africa/Brazil variant of SARS-CoV-2. .. However, no samples in this study showed SD Biosensor V1-negative and V2-positive results, which would suggest antibodies to the South Africa/Brazil SARS-CoV-2 variant. .. All SD Biosensor V2-positive samples (165/165) showed V1-positive results, whereas 43 of 208 V1-positive samples (20.7%) showed V2-negative results.

    Article Snippet: .. The positive rates seven months after the first injection for all the assays were decreased (97.0% for Abbott IgG, 86.0% for Siemens IgG, 98.0% for SD Biosensor V1, 92.0% for SD Biosensor V2, and 66.0% for the GenScript assay) when compared to the rates after the second dose, except for Roche total (100.0%). ..
