      Saliva not as good as swab - 84% sensitivity; similar results to @drdebwilliamson https://twitter.com/CMIJournal/status/1262267423681462272 …

      Saliva is easier to collect and may help address those in Victoria who are refusing to be tested.

      Studies have mostly found saliva to miss a few cases compared to the other swabs, but perhaps that has been overcomehttps://twitter.com/peripatetical/status/1262543733377003524?s=20 …

      At this stage a nasal swab is still thought to be better (and is related to technique - probably most sensitive when done by an ENT surgeon!). Saliva could be as good but needs optimising - eg using greater volumes in the test, or centrifuging the specimen first.

      The crew at the Doherty Institute @TheDohertyInst in Victoria have been hard at work looking into making saliva testing useful, (good for kids although viral loads here may add to issues). I'd imagine it'll be getting a good trial right now in Victoria 🧪https://www.doherty.edu.au/news-events/news/use-of-saliva-as-a-diagnostic-specimen-for-covid-19 …
