England To Suspend PCR Confirmation Of +ve Rapid Covid Tests - 0 views

  •  
    People who test positive for Covid-19 on rapid lateral flow tests will not need to confirm their results with a follow-up PCR test if they are not showing symptoms, the UK Health Security Agency said on Wednesday (January 5). Britain is reporting record daily case numbers, and the UKHSA said that the high prevalence meant the chance of a false positive from a lateral flow device (LFD) was low. The move could also reduce the burden on the testing system, and reduce confusion if the test results contradict each other. At current levels of prevalence, officials say a positive LFD result is likely to be accurate, even if a follow-up PCR were negative. "While cases of Covid continue to rise, this tried-and-tested approach means that LFDs can be used confidently to indicate Covid-19 infection without the need for PCR confirmation," said UKHSA chief executive Dr Jenny Harries.

No indication Of Omicron Wave Yet: UK Health Chief - 0 views

  •  
    There is no sign of a surge of the Omicron coronavirus variant in Britain so far, the chief of the UK Health Security Agency said on Tuesday, adding that there was no rise in the proportion of tests with a quirk that distinguishes it from Delta. Jenny Harries said there were five confirmed Omicron cases in England and 10 "highly likely" cases, but that was not a sign of an increase in "S-gene target failure" in PCR tests in Britain, which is a feature of Omicron. "Right across the country we watch for… S-gene target failure, which is a sort of proxy measure," Harries told BBC radio. Cases with S-gene target failure can then be prioritised for full genomic sequencing.
