ACCURUN® Anti-SARS-CoV-2 Reference Material Kit offers positive materials for antibodies to the SARS-CoV-2 virus. Also included are complementary negative materials. The kit is designed to support assay installation and monitoring of day-to-day assay performance, providing a complete quality solution for SARS-CoV-2 antibody testing. Series 1000 is designed for IgG-specific assays and is released using the Abbott ARCHITECT SARS-CoV-2 IgG assay. Reference materials are specifically formulated to exhibit low positive reactivity in true patient-like matrices, to test assay performance near critical signal cutoff boundaries.
