There was no notable difference in detection ability between saliva and tracheal secretion (average hit rates 85.1 and 87.7%, respectively). The device recorded automatically the number and time length of each nose dip into the scent holes and the location of the positive and negative samples. All dogs had a high diagnostic specificity with a small range in variation, which could be important for population screening to avoid false positive results. Saliva samples and tracheobronchial secretion samples were collected from hospitalised COVID-19 patients that showed clinical symptoms and were diagnosed as SARS-CoV-2 positive using nasopharyngeal swab samples. This will be recorded by the device. YOOS™ Free Sample (For U.S. BMC Infectious Diseases View: Min: $ 0. Angle C, Waggoner LP, Ferrando A, Haney P, Passler T.

In the upper left corner of the video, one can see how the figures change depending on the detection behaviour of the dog (true positive [correct indication; n = 3], true negative [correct rejection; n = 8], false positive [incorrect indication; n = 0], and false negative [incorrect rejection; n = 1]). Future studies are needed to address this including a higher number of different samples to evaluate the analytical sensitivity (e.g. Hoffmann:https://www.dvg.net/fileadmin/Bilder/DVG/PDF/20-03-31-LA RT qPCR_SARS-CoV- 2_IP4__AgPath_.pdf.
