2 (68.4-87. for sCOVG using the manufacturer's cutoff. The NPA was 100 % (87.1-100.0 and 85.13-10 for both assays. Dilution studies revealed 100% (95% CI 90.8-100%) qualitative agreement between specimen types on the COV2T assay and 98.0% (88.0-99.9%) with the sCOVG using study defined cutoffs. DBS specimens demonstrated high PPA and NPA relative to plasma for SARS-CoV-2 serological testing. Our data support feasibility of DBS sampling for SARS-CoV-2 serological testing. DBS specimens demonstrated high PPA and NPA relative to plasma
