The government is only using just over half of its daily coronavirus testing capacity, according to the latest official statistics.

Alok Sharma, the Business Secretary, told today's Downing Street press conference that 21,328 tests were carried out yesterday.

But No10 has estimated the UK's testing capacity is now at 38,000 a day, with ministers continuing to struggle to explain why actual test numbers are falling so far short of what could be done.

The latest data came after Matt Hancock admitted his 100,000 daily coronavirus tests target is an 'ambitious goal' as he was confronted by health chiefs over claims NHS staff are not coming forward for the checks.

Dame Donna Kinnair, the chief executive and general secretary of the Royal College of Nursing, said she had been told examples from the frontline of sick nurses who were driving two hours to testing centres only to be told to come back another day.

She said: 'Nurses are sometimes driving two hours feeling very unwell with possible symptoms of coronavirus and driving to a testing station.

'Sometimes if you haven't got an appointment you're turned away only to be told to come back another time.

'We need clear instructions about how to get tested so that people aren't turned away, we can make appointments and people who are feeling very unwell have access to tests.'

Meanwhile, a senior practice nurse in north London has labelled the testing operation 'an absolute disgrace' after she was forced to stay at home for a month due to the fact she could not access a test.

Those comments are in stark contrast to the claims made by the Health Secretary who has argued lower than expected demand among NHS staff has allowed the government to expand its operation to other public sector workers.

Jeremy Hunt, who chairs the health committee, has called for a massive increase in testing and tracing.

He said it was a huge logistical undertaking but added: 'If we're going to copy the best in the world then that is what we now need to do.'

Earlier this week Mr Hancock announced tests would be extended across the social care setting and today he said the police, fire service, prison staff and judges will also now be eligible.

Earlier Matt Hancock had told the Health and Social Care Select Committee that coronavirus testing will be expanded to more public sector workers including police and the fire service

But Dame Donna Kinnair from the Royal College of Nursing challenged Mr Hancock's claims that demand for tests from NHS workers had dropped as she said nurses were still struggling to access checks

Mr Hancock had said there was lower than expected demand for tests from NHS workers over the Easter weekend.

But healthcare bosses have cast doubt on his claims of a reduction in demand amid suggestions that the flat numbers could actually be down to testing failures and poor access to checks for workers.

Dame Donna told the Health and Social Care Select Committee: 'There is an issue about how we get nurses and others to be able to be tested because actually it's not quite clear.

'So you would expect as an employer, that if you started to become ill that you would be able to have a defined place to go to, and your employer would instruct you where to go.

'What I'm hearing from the frontline is that nurses are driving up to two hours, feeling very unwell with possible symptoms of coronavirus and driving to testing stations, and sometimes if you haven't got an appointment you're turned away only to be told to come back another time.

'So we really need some clear direction of how we can access testing, both in the NHS but more so for social care because [they] don't have the same infrastructure as the NHS.'

The Covid-19 testing site at Chessington was working efficiently today after a slow start at the beginning of the process.

Scores of NHS staff and other key workers queued in an orderly fashion for the 90- second swan examination which will determine whether they have had Coronavirus or not.

Four testing booths were in operation today compared to only one when the centre first opened earlier thus month.

Key workers queued in six lanes ahead of their test with their windows closed but their ID documents and email invitation to the site on display.

Hundreds of vital staff members are believed to have passed through the site enabling to return to their frontline jobs once their symptoms have past.

Testing currently is a split between patients, NHS staff and social care workers. Self-isolating staff are able to get tested at one of the UK's 22 drive-through sites.

Barbara Botsford, a nurse in London, told the Evening Standard she was unable to work for a month due to testing access problems.

She said she had to wait weeks for a test after self-isolating, finally got one, was then told it had been lost and that she would have to be tested again before the original then appeared showing she had tested negative.

Ms Botsford said she had been 'desperate' to return to work but had been prevented from doing so for four weeks because of the testing 'fiasco'.

Mr Hancock told the same committee that the current NHS coronavirus-related staff absence rate is 7.1 per cent, down slightly on the previous statistic of eight per cent.

The Health Secretary has said he is sticking to his 100,000 tests target but today insisted 'ramp up' was happening even before he made the promise.

'I don't think if we had announced the 100,000 target a couple of weeks earlier as you suggest we would be in any different position now because we were continuing to drive to increase testing all along,' he told MPs.

'The challenge is that the increase, the radical increase, in the amount of testing over the last two months from 2,000 tests a day at the start of March to 10,000 tests a day at the end of March and now with the ambitious goal I have set of 100,000 by the end of this month.

'That ramp up has been ongoing throughout. I set a public target in part because people were asking how fast are we going to get there and because it also managed to galvanise the non-diagnostic pharmaceutical industry here.'

Mr Hancock said that now 'we have got the curve under control, I want to be able to get back to the position that we can test everybody with symptoms'.

'I anticipate being able to do that relatively soon because we are increasing capacity,' he said.

Announcing a further expansion of testing to more public sector workers he added: 'I can today expand the eligibility for testing to police, the fire service, prison staff, critical local authority staff, the judiciary and DWP staff who need it.

'We are able to do that because of the scale up of testing.'

As well as NHS staff key workers are also being given priority to bid to Visit one of five mobile test bays at the Wembley site.

Trained staff take a nasal and throat swab with results being emailed out in 48 hours.

More than 500 people had an appointment on Friday with a similar number throughout the week

Those arriving need written authorisation to enter one of five testing bays.

Members of the public are not yet permitted to attend.



Yesterday it emerged that Mr Hancock had failed to hit a target of carrying out 25,000 daily coronavirus tests.

The Department of Health announced on March 18 that testing for coronavirus would increase to 25,000 a day 'within four weeks' with that period now having elapsed and the number of tests still below even 20,000.

At least £16million has already been wasted on two million coronavirus antibody tests from China that turned out to be duds.

Boris Johnson heralded the tests as a 'game changer' but the Government is now seeking a refund from two manufacturers following a negative evaluation by Oxford University experts.

Antibody test kits, which check the blood for antibodies produced after somebody has contracted the virus, are seen as vitally important to reactivating the economy and measuring national immunity rates.
