More than 1,300 people received news that they had mistakenly tested positive for coronavirus, according to the Ministry of Health and Social Affairs (DHSC).
A lab error with NHS Test and Trace means 1,311 people who took a test across the UK between November 19-23 were falsely reported they had Covid-19.
The DHSC said there was a problem with a batch of test chemicals which meant those results were void, reports PA.
A DHSC spokesman said, “Swift action will be taken to notify those affected and asked to do another test and continue to self-isolate if they have symptoms.
“This laboratory error was an isolated incident and is currently being fully investigated to ensure it does not recur.”
The DHSC did not comment on whether the bug affected the current regional numbers of infection rates.
The NHS test and trace program was hampered by operational issues. The numbers earlier this week show that around four in ten contacts of those who test positive for the virus are still not reached.
The Prime Minister announced in his winter plan on Monday (Nov. 23) an additional £ 7 billion for Test and Trace to improve testing and improve contact tracing.
This commitment will bring total funding for Test and Trace to £ 22 billion this fiscal year, which has received some criticism.
The number is almost a fifth of the total annual NHS budget.
But Boris Johnson firmly believed the system was “value for money”, despite admitting that there were “teething troubles”.
