An important study validating use of saliva for PCR testing as opposed to a nasopharyngeal swab.
We have been using expectorated phlegm for PCR testing for some tests for the past several weeks because of a lack of swabs, which is a brobdingnagian problem nationwide for ramping up testing. This was internally validated apparently but nothing published on it. Also we were not using plain old saliva which is even easier than having to teach a patient to give a good expectorant sample.
Saliva samples would obviate need for swabs which are in short supply and also allows at home sample collection to reduce PPE usage.
This is very good news that opens up some helpful options for the future, if our leaders can be convinced that developing the infrastructure for good tracking and quarantine is important to save lives and the economy.
