1.Elliott said that “clinical experiences” suggested that as many as 30% of nasal swab tests result in a false negative, where people are wrongly told they do not have the virus.
2.The Guardian has also learned that the government is in advanced discussions with one of the biggest saliva test companies in the US about getting approval for its product to be used in the UK.
3.The California-based firm, Curative, which is run by an award-winning UK scientist, has told officials it can provide 100,000 tests a week immediately, with the potential for capacity to be massively expanded if it gets the go-ahead. The company is providing tests for the US air force and said it had carried out more than 300,000 tests in five states including Texas and California.
4.Beales said his team had found that saliva samples were “superior” to nasopharyngeal swabs for detecting Covid-19 because they remove almost all possibility of “operator failure”.
