Article Synopsis
- - The study evaluates the effectiveness of nasal swabs (NS) versus nasopharyngeal swabs (NPS) for detecting SARS-CoV-2 using nucleic acid amplification tests (NAAT) and quantitative SARS-CoV-2 antigen tests (QAT).
- - Results showed that NS had lower agreement rates with NPS for both NAAT (76.7%) and QAT (65.0%), along with higher cycle threshold (Ct) values, indicating a lesser ability to detect the virus compared to NPS.
- - Despite its limitations, NS may still be beneficial for detecting high viral loads in early-stage COVID-19 patients, as most NS tests were positive in cases with significant viral presence. *
Introduction: Highly sensitive reagents for detecting SARS-CoV-2 antigens have been developed for accurate and rapid diagnosis till date. In this study, we aim to clarify the frequency of false-positive reactions and reveal their details in SARS-CoV-2 quantitative antigen test using an automated laboratory device.
Methods: Nasopharyngeal swab samples (n = 4992) and saliva samples (n = 5430) were collected.
