The UK Government is coming under increasing pressure over Covid-19 tests as healthcare leaders warned there is "no immediate prospect" of mass NHS staff testing.
Chris Hopson, the chief executive of NHS Providers, which represents NHS trusts, said maximum testing capacity in the UK was currently "very constrained" at around 13,000 tests per day.
At present, the focus is on testing patients in hospital to see if they have coronavirus, with NHS trusts told earlier in the week they should use up to 15% of any spare testing capacity for NHS staff.
Health Secretary Matt Hancock has now scrapped that cap, telling NHS hospital labs to use all spare capacity to test their frontline workers.
