A Case Report of a COVID-19 Infection with Positive Sputum and Negative Nasopharyngeal Rapid Antigen-Based Testing: A Practical Method to Explore Sputome

2023-01-29

Abstract excerpt

Current COVID-19 antigen testing is primarily carried out by obtaining a specimen via nasopharyngeal swab and performing a rapid lateral flow immunoassay (LFIA) or related immunoassays. On average, a nasopharyngeal antigen-based LFIA for COVID-19 remains positive for approximately one week from symptom onset, and levels of infectivity and duration of the symptoms may depend primarily on carrying a high viral load...
