The ability of biodetection canines to detect COVID-19 odours from clinical samples

This study evaluated the performance of Getxent tubes in collecting the odor of patients to determine if they are infected with COVID-19.

Odor samples were collected in two ways:

1. Getxent tube placed under both armpits for 10 minutes.
2. Getxent tube suspended above a saline gargle specimen in a glass jar, sealed for 24 hours.

The results are:

• 100% of dogs detected the presence of COVID-19 in infected individuals, regardless of the sampling procedure with Getxent tubes.
• 100% of dogs did not alert to blank Getxent tubes.

This demonstrates that Getxent tubes are odorless and can reliably collect odor samples from patients, enabling dogs to detect COVID-19 infected individuals.
