Prof John Newton, who is co-ordinating coronavirus testing for the government, said these new mobile testing units would help achieve the goal of performing 100, 10 tests a day by “providing tests to vital frontline workers wherever they need them”.
He said efforts to increase capacity had resulted in “scores of new testing facilities and Britain’s largest network of diagnostic labs in history”.
Since Friday, millions of key workers and people they live with have been able to book appointments online to be tested. Those too ill to travel should also be able to order home kits – although numbers are limited.
Since the website opened, slots for these tests have been booked up within hours and applications have had to close because of high demand.

Labor leader Sir Keir Starmer has called on the PM to set out an “exit strategy” for lifting the lockdown.
In a letter to Mr Johnson, Sir Keir said the UK was in danger of falling behind other countries again – including the devolved administrations in Scotland and Wales – which were already engaged in “adult” conversations with their citizens as to how the restrictions could be eased.
“Simply acting as if this discussion is not happening is not credible, especially when other governments and our own devolved administrations have been able to communicate so much more, “he wrote.
At the daily No briefing on Saturday, Home Secretary Priti Patel said the government was working towards returning the UK to normal, but said it was still too soon to begin easing up.
“We know that people are frustrated but we are not out of danger yet,” she said.
NHS England medical director Prof Stephen Powis said the virus would start to “spread more” if social distancing measures were lifted.
Meanwhile, the British Medical Association (BMA) has accused ministers of dragging their feet. over calls for families of healthcare workers who lose their lives fighting coronavirus to be financially supported.
The doctors’ trade union said it had written twice to the chancellor raising the issue, but had yet to receive a response.
The government said it was currently considering the financial support for the families of those on the front line.
The BMA has also called for all key workers to be provided with face masks to combat the spread of the virus.
BMA chairman Dr Chaand Nagpaul told the Daily Telegraph that giving masks to “transport workers, shopkeepers, carers or supermarket staff” would offer “a level of protection, however small “.
He added:” The government must pursue all avenues of reducing the spread of infection. This includes asking the pub lic to wear face coverings to cover mouths and noses when people leave home for essential reasons. “
