  • [Pre-print, not peer-reviewed] A systematic review (n = 83 studies) of the diagnostic accuracy of SARS-CoV-2 rapid antigen lateral flow testing (RALFT) compared to RT-qPCR among symptomatic and asymptomatic individuals found the overall sensitivity for RALFT was 75%, and the sensitivity was higher among symptomatic individuals. Viral load was the most important factor for test sensitivity, but other factors, such as specimen storage and anatomical collection type, also affected performance. RALFT and RT-qPCR testing were both highly sensitive compared to viral culture.
