2 days ago · New research shows that, in a head-to-head comparison of five tests used to detect COVID-19 antibodies (known as ‘immunoassays’), an assay manufactured by Siemens and one developed by an academic partnership led by the University of Oxford had the most accurate results.
4 days ago · Background During the COVID-19 pandemic, antigen diagnostic tests were frequently used for screening, triage, and diagnosis. Novel instrument-based antigen tests (iAg tests) hold the promise of outperforming their instrument-free, visually-read counterparts. Here, we provide a systematic review and meta-analysis of the SARS-CoV-2 iAg tests’ clinical accuracy. Methods We systematically ...
2 days ago · Neutralizing antibody tests have been a critical tool in the fight against infectious diseases, particularly during the COVID-19 pandemic. These tests are used to determine the presence of antibodies in the blood that can neutralize pathogens, such as viruses, and prevent them from infecting cells.

4 days ago · The most common note topic was adverse events (51%), followed by conspiracy theories (37%), vaccine recommendations (7%), and vaccine effectiveness (5%). Nearly all (97%) of the notes were accurate, 2% were partially accurate, and 0.5% were inaccurate.
5 days ago · This study follows 99 subjects vaccinated with Pfizer/BioNTech COVID-19 vaccines over two years, with particular focus on the last year of observation (between days 360 and 720). The response to the vaccination was assessed with Diasorin’s SARS-CoV-2 TrimericSpike IgG. Screening for SARS-CoV-2 infection was performed with Abbott’s SARS-CoV-2 Nucleocapsid IgG immunoassay. Data from ...
2 days ago · The results suggest that previous infection, together with vaccination, offers strong protection against the original COVID-19 strain. People who do not have antibodies against a particular infectious agent are ‘seronegative’ and those who have antibodies are called ‘seropositive’.
