Hon CHRIS HIPKINS (Minister for COVID-19 Response): Yes. We continue to review our settings based on emerging information about the virus and emerging trends in test technology globally. However, more work needs to be done on the comparison around the sensitivity between a saliva sample and a nasopharyngeal swab. It's important that we use the best diagnostic tools to suit our settings and context to ensure that the detection of COVID-19 is done as early as possible. We understand that experts in Australia have signalled similar concerns regarding the use of saliva samples in their context, which is actually very similar to our own.
