The tester is required to use a swab to collect samples from the deep nasal cavity or the back of the throat of the suspected patient, while the saliva test only requires the saliva of the suspected patient to be collected.
On the one hand, due to the simple operation of self collecting saliva, we can greatly increase the number of daily tests; On the other hand, medical staff need to face a great risk of infection when collecting samples from the nasopharynx or oropharynx. The use of saliva detection will protect the safety of medical staff and use precious protective equipment for clinical treatment rather than testing.
Saliva samples need to be stored and transported at normal ambient temperature and handed over to the tester within 48 hours after collection - you only need to go to the drive in test point, and the tester will give you the collection device. You spit your saliva inside, disinfect the outer wall of the device with alcohol and return it to the tester. The test results can be received in 24-48 hours.
