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.
