Why saliva based testing

> Pain and discomfort free

> No contact sampling for enhanced safety

> Self sampling, reducing/eliminating testing queues

> Rapid processing for client convenience

> As accurate as nasal/oral swabs 

Saliva collection.jpeg

> Enables large scale testing due to self collection

> Enables testing of young children without discomfort

> Implementation in UK, New Zealand, India & Australia (news links below)

Several peer reviewed scientific studies have compared nasopharyngeal swabs and saliva samples in confirmed COVID-19 patients and healthcare workers.


The studies found that:

  • Using saliva for COVID-19 detection is more sensitive and consistent than using nasopharyngeal swabs.

  • Less variability occurred in sample collection of saliva.

  • COVID-19 was detected in the saliva of asymptomatic healthcare workers, whereas COVID-19 was not detected from nasopharyngeal swabs in the same workers.

The literature detailed below shows that saliva is a reliable sample and more sensitive than nasopharyngeal swabs.
