Xie JW, Zheng YW, Wang M, Lin Y, He Y, Lin LR. For diseases that are primarily respiratory in nature, like COVID-19, nasopharyngeal swabs have been the most reliable, as they sample an area of the respiratory tract where the virus appears to first infect an individual. All sampling methods had a test specificity of 100% regardless of the cycle threshold (CT) value. Ready to use, no need for additional equipment. In people with confirmed COVID-19, antigen tests correctly identified COVID-19 infection in an average of 73% of people with symptoms, compared to 55% of people without symptoms.
