Scientists develop 'transformative' saliva Covid-19 test

The tests use a saliva sample in a tube which undergoes hypercube sample pooling to allow dozens of samples to be PCR-tested simultaneously

A university is trialling the use of saliva samples to test for Covid-19, a move researchers claim could be “transformative” for screening large numbers of people and cuts the risk of community transmission.

Scientists behind the pilot TestEd scheme at the University of Edinburgh said it is potentially more accurate, less invasive and cheaper than current tests.
