Abstract Introduction Antibodies to SARS-CoV-2 serve as critical diagnostic markers for
determining how broadly the COVID-19 pandemic has spread, confirming patient recovery …

Objectives To illustrate how patient risk and clinical costs are driven by false-positive and
false-negative results. Methods Molecular, antigen, and antibody testing are the mainstay to …

ABSTRACT The Elecsys Anti-SARS-CoV-2 immunoassay (Roche Diagnostics) was
developed to provide accurate, reliable detection of antibodies to severe acute respiratory …

Objectives Serological studies have been critical in tracking the evolution of the COVID-19
pandemic. Data on anti-SARS-CoV-2 antibodies persistence remain sparse, especially from …

Rapid point-of-care tests (POCTs) for detection of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2)-specific antibodies vary in performance. A critical need exists …

Background These last months, dozens of SARS-CoV-2 serological tests have become
available with varying performances. A major effort was completed to compare 17 …

The COVID-19 outbreak has had a major impact on clinical microbiology laboratories in the
past several months. This commentary covers current issues and challenges for the …

We used commercially available ELISAs to test 68 samples from coronavirus disease cases
and prepandemic controls from Benin. We noted< 25% false-positive results among …

Waning humoral immunity in coronavirus disease patients has raised concern over
usefulness of serologic testing. We investigated antibody responses of 58 persons 8 months …

Background Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
