Covid-19快速抗原检测持续假阳性 Persistent False Positive Covid-19 Rapid Antigen Tests N Engl J Med 2024;390:764-5 Herbert C, McManus DD, Soni A. 致编辑: 严重急性呼吸综合征冠状病毒2(SARS-CoV-2)快速抗原检测在急性感染的诊断中发挥重要作...
As more people are vaccinated or have already had the virus, many believe we should be moving toward rapid antigen testing instead of PCR testing because a positive test that doesn't actually pose a health threat can have significant consequences. The state's own guidance fordiscrimination and i...
The false-negative rate in the early phases of the pandemic has been reported to range from 2% to 29%. The specificity of molecular RNA assays is excellent. ANTIGEN Tests detect viral proteins, e.g., SARS-CoV-2 spike protein. Data from 2022-2023 found lower sensitivity of an...

For those who test positive in low prevalence settings, the high false positive rate means that mitigation strategies, such as molecular testing to confirm positive results, are needed. Ag-RDTs, when used appropriately, are promising tools for scaling up testing and ensuring that patient management...
and once again circulate more widely. Upcoming influenza seasons could therefore be compounded in severity as immunity wanes over time for all age groups24. Moreover, the continued evolution of regionally distinct lineages increases the risk that the antigens included in the vaccine will not be rep...
A low event rate for death, ICU care, or ventilator therapy precluded assessment of hypogonadism as a risk factor for severe COVID-19. Also, because most hospitalizations were during the first year of the pandemic, when COVID-19 vaccines were not available (eFigure 2 in the Supplement), ...
Positive fold change indicates higher proportion in mild COVID samples. FDR refers to false discovery rate calculated from moderated t test using Benjamini and Hochberg correction for multiple comparisons. See STAR Methods for differential abundance testing statistics.

syndrome, a debilitating condition resembling certain symptoms of PACS, as well as an increased rate of respiratory infections18,27. PACS has been proposed to result from tissue damage due to direct effects of the virus, excessive inflammation, or thrombotic events; alternatively, PACS could be ...
The Benjamini–Hochberg False Discovery Rate (FDR) approach was employed to narrow down genes and maintain statistical significance. The criterion used was Padj < 0.05 and |log2FoldChange (FC)| > 1. The heatmaps and volcano plots were constructed using the "Pheatmap", "Enhancedvolcano”...
