COVID testing has been suspended at a private laboratory in Wolverhampton after an estimated 43,000 people were given incorrect results.
An investigation was launched into reports of people receiving negative PCR test results after they had previously tested positive on a lateral flow device.
NHS Test and Trace estimates that 400,000 coronavirus test samples were processed through the Immensa Health Clinic lab in Wolverhampton – and an estimated 43,000 people may have been given incorrect results between 8 September and 12 October.
The UK Health Security Agency (UKHSA) said most were in the South West of England.
It insisted there are “no technical issues” with the lateral flow or PCR tests, adding that other labs are “working normally” and described it as an “isolated incident attributed to one laboratory”, but said all samples are now being redirected to other labs.
Test and Trace is contacting people that could still be infectious to advise them to take another test, while close contacts who are symptomatic will also be urged to get tested.

Samples that would have gone to the lab are now being redirected to others.
Dr Will Welfare, public health incident director at the UKHSA, said: “We have recently seen a rising number of positive LFD results subsequently testing negative on PCR.
He added there is “no evidence of any faults” with the lateral flow or PCR test kits themselves and “the public should remain confident in using them and in other laboratory services currently provided”.
“If you get a positive LFD test, it’s important to make sure that you then get a follow-up PCR test to confirm you have COVID-19. If you have symptoms of COVID-19, self-isolate and take a PCR test,” he said.
Immensa Health Clinic Ltd boss Andrea Riposati said: “We are fully collaborating with UKHSA on this matter. Quality is paramount for us.
“We have proudly analysed more than 2.5 million samples for NHS Test and Trace, working closely with the great teams at DHSC and UKHSA. We do not wish this matter or anything else to tarnish the amazing work done by the UK in this pandemic.”
The Welsh government said it heard last week of reports that a “higher than expected” number of positive lateral flows were resulting in negative PCR tests.
Around 4,000 people in Wales may have been given “inaccurate results” from tests processed at the affected laboratory in Wolverhampton and the majority will have been taken at testing sites across the Gwent and Cwm Taf Morgannwg areas, health minister Eluned Morgan said.
Another centre, this time in Berkshire, advised people to get retested over fears they were wrongly given negative results.
The official advice comes after some PCR tests at the government-run COVID testing site Newbury Showground resulted in false negatives.
It comes as fully vaccinated people arriving in England from countries not on the red list have been told they can take a cheaper and quicker lateral flow test rather than the PCR version from 24 October.
Transport Secretary Grant Shapps said the switch requires honesty from passengers.
Speaking to Sky News, Mr Shapps was pressed on how lateral flow results will be verified and he said travellers will take a photo and upload it, describing it as “straightforward and pretty quick to do”.
He said: “Like so many laws in this country, we ask people not to do things and put societal restrictions on people.
“We don’t have a policeman on every corner, in every home, to make sure people aren’t breaking the law.”
People whose homes have been destroyed by the floods sweeping across parts of the UK over the past couple of days have been telling Sky News how they coped with the deluge.
In Lincolnshire, where a major incident has been declared, Terry, from Grantham, showed a Sky crew the aftermath of the deluge in his home, which was left under two feet of water.
“Everything’s gone,” he said, adding that he was “devastated”.
The first sign of trouble came at lunchtime on Monday, when his wife woke him and said there was water coming in [to the house], and “within a few minutes, the whole house was flooded”.
They rushed their belongings and pets upstairs, he said, as he revealed the damage to the flooded living room and kitchen, where the water mark was above a power socket.
Terry said the kitchen, where the floor was covered in sludge, smelled of mud and sewage, and their furniture and carpets were wrecked.

They have no electricity and the food in the cupboards and freezer was “completely ruined”.
Graham Johnson, who lives in a boat with his wife and dog, in the village of Barrow upon Soar in Leicestershire, was in the pub on Monday night, before the water started to rise “rapidly”.
People living in a local caravan park were moved as a severe flood warning was issued.
Mr Johnson said he had gone out “for a couple of pints as usual and, the next thing we know, bingo”.
The couple feared their boat home was about to be swept towards the bridge.
“That’s our pride and joy, where we live, and we didn’t want to lose it,” he said, as he praised the “fantastic” emergency services, who rescued them and their dog after a nervy three-hour wait.
They were two of the 59 people rescued by firefighters in the county, where a major incident was declared and crews were called out to 160 flood-related incidents, the Fire Brigades Union (FBU) said.
Another Leicestershire resident whose home was inundated was Qasim Abdullah from Loughborough.

Flooding across East Midlands
Pictures taken by the Associated Press show him walking through almost knee-deep water in his living room.
In nearby Quorn, businesses have shut as the main high street has flooded for the second time in as many years.
Two of the pubs in particular have been damaged.
Last year, residents had to launch a crowd fundraiser to help pay for the costs of renovation. Not to mention soaring insurance premiums.
Indy Burmi, who owns a hair salon and restaurant, hasn’t suffered flooding, but said he’s had to close up and cancel all Tuesday’s reservations, as his clients simply can’t get into the village.
And, with more rain forecast, conditions could get even worse in the short term, while residents worry that an annual battle with rising water is now the new normal.
Elsewhere in the UK, the next danger is from ice forming on untreated surfaces after rain on Tuesday evening, the Met Office has said, as it issued a new warning for northern England and Wales from 5pm until midday on Wednesday.
The Royal Liverpool University Hospital has declared a critical incident due to “exceptionally high” demand on A&E and patients being admitted to wards.
The hospital said there had been a spike in people with flu and respiratory illnesses going to emergency departments in recent weeks.
A spokesperson for the hospital said it had a “comprehensive plan in place” and was “taking all the necessary actions to manage the challenging circumstances”.
“We are working with partner organisations to ensure those that are medically fit can leave hospital safely and at the earliest opportunity,” they added.
The hospital warned some people would experience delays as it prioritises the sickest patients.
People whose case isn’t an emergency are being asked to see their GP, pharmacy or walk-in centre – or call the 111 service for advice.

The Royal Liverpool University Hospital is in the city centre and is the biggest hospital in Merseyside and Cheshire.
Declaring a critical incident can happen when a hospital is experiencing exceptional demand, or sometimes if there is a serious problem with staffing levels.
It indicates it can’t function as normal and allows it to take extra measures to protect patients, such as prioritising the most unwell people and getting support from other agencies.
It could last hours, a few days, or weeks if necessary.
A critical incident was also declared on Friday by the NHS Cornwall and Isles of Scilly Integrated Care Board.
It said it had seen almost four times as many inpatients compared with last year and urged people with flu to avoid going to A&E.
