Figure 1. Cycle Threshold (Ct) Values from Tongue, Nasal, and Mid-Turbinate Swabs Collected by Patients Relative to Those from Nasopharyngeal Swabs Collected by Health Care Workers.
The correlation coefficient is superimposed on each panel, along with a trend line estimated with the use of simple linear regression. Plots show the available Ct values for 43 patients who had positive test results from both tongue and nasopharyngeal swabs (Panel A), 46 patients who had positive test results from both nasal and nasopharyngeal swabs (Panel B), and 48 patients who had positive test results from both mid-turbinate and nasopharyngeal swabs (Panel C). Data on 4 patients (1 patient with positive test results from both tongue and nasopharyngeal swabs, 1 patient with positive test results from both nasal and nasopharyngeal swabs, and 2 patients with positive test results from both mid-turbinate and nasopharyngeal swabs) were not included in this analysis because multiple swabs obtained from these patients were labeled with a single test site (i.e., tongue, nasopharynx, nose, or middle turbinate).
