Diagnostic Accuracy of the Abbott BinaxNOW COVID-19 Antigen Card Test, Puerto Rico.
Influenza Other Respir Viruses
July 2024
Division of Vector-Borne Diseases, Centers for Disease Control and Prevention, San Juan, Puerto Rico.
Background: The COVID-19 pandemic underscored the need for rapid and accurate diagnostic tools. In August 2020, the Abbott BinaxNOW COVID-19 Antigen Card test became available as a timely and affordable alternative for SARS-CoV-2 molecular testing, but its performance may vary due to factors including timing and symptomatology. This study evaluates BinaxNOW diagnostic performance in diverse epidemiological contexts.

Article Synopsis
- * A study conducted between September 2018 and October 2022 in Tennessee and Georgia found that 12.1% of hospitalized adults with CAP had Streptococcus pneumoniae detected, with the most common serotypes being 3, 22F, 19A, and others.
- * Findings suggest that a significant portion of detected serotypes, approximately one-third, are not covered by current vaccines like PCV15 and PCV20, indicating the need for new vaccines with broader serotype coverage to reduce disease occurrence.
Implementation and Performance of a Point-of-Care COVID-19 Test Program in 4000 California Schools.

Center for Laboratory Services, California Department of Public Health, Richmond, CA.
Article Synopsis
- The study assessed a California COVID-19 antigen testing program in K-12 schools, involving self-swabbing and testing by trained school personnel, from August 2021 to May 2022.
- It included over 944,000 participants, with results showing the Abbott BinaxNOW antigen test had an 81.2% sensitivity and a 99.6% specificity compared to PCR tests.
- The findings concluded that a school-based testing program is feasible and effective, offering a model for managing future infectious disease outbreaks.
Comparative Performance of COVID-19 Test Methods in Healthcare Workers during the Omicron Wave.
Diagnostics (Basel)

Department of Medicine, Division of Infectious Diseases, Oregon Health and Sciences University, Portland, OR 97239, USA.
The COVID-19 pandemic presents unique requirements for accessible, reliable testing, and many testing platforms and sampling techniques have been developed over the course of the pandemic. Not all test methods have been systematically compared to each other or a common gold standard, and the performance of tests developed in the early epidemic have not been consistently re-evaluated in the context of new variants. We conducted a repeated measures study with adult healthcare workers presenting for SARS-CoV-2 testing.

Pneumonia is a major cause of death among adults living with HIV in South Africa, but the etiology of many cases remains unknown. This study evaluated the utility of a nanofluidic qPCR assay to detect and serotype Streptococcus pneumoniae in urine samples from patients hospitalized with community-acquired pneumonia (CAP). The nanofluidic qPCR assay was optimized to target 13 pneumococcal serotypes and 4 reference genes.
