What is it about?
The best anatomical sites for collecting COVID-19 test samples were found to be the nasopharynx and nostrils in our comparison study. We evaluated the performance of saliva, nostrils, throat swab, and the usual standard nasopharynx. Patients themselves collected the saliva and nostril samples.
