The Welsh Government hopes to ease the testing shambles in the country by pumping more of their own resources into the programme.
Health minister Vaughan Gething said they planned to mobilise more of their mobile units and increase capacity at drive through centres to try to deal with a massive backlog in coronavirus testing.
Wales is currently heavily reliant on the UK Government's testing system, which has buckled under the pressure of more people seeking tests as we head into autumn and schools return.
It has seen people left unable to get a test, or being sent miles from home to be given one.
Speaking to BBC Radio Wales, Mr Gething said they hoped to have more capacity in the system within the next week as they shift their own resources into the system as a short-term fix.
He said: "We want an urgent discussion [with the UK Government] about how quickly we want those issues to be resolved.
"In the mean time we're already looking at what we can do with our own testing resources in Wales.
"So we're going to have more mobile units switched this week, I expect we're going to have five extra ones, which are going to run through our Public Health Wales laboratories so they won't be affected by the pinch points [in the UK system].
"We're also looking at opening additional lanes in the drive through centres, where again, those can then go to Public Health Wales laboratories that will practically increase capacity and it should also mean we're not putting more tests into the Lighthouse system."
He added: "It's a real point of concern and I understand the real frustration of people in Wales which is why we're having to move rapidly our own resources here in Wales."

He said capacity in Wales could be moved into public facing testing as they believed they currently had enough capacity for testing in the health service.
But he said testing capacity could not immediately be moved to help the public, adding it was "not as easy as flicking a switch".
He said problems got worse over the weekend, and said "it has been a declining picture over the past couple of weeks", which was why they were now taking action.
Mr Gething said the backlogs at Lighthouse testing centres needed to be dealt with quickly ahead of the need for more capacity in Autumn and Winter.
UK health secretary Matt Hancock admitted that it might be "a matter of weeks" before the testing problems are resolved, and on Tuesday announced that tests in England will be rationed.
He said there would be "prioritisation" of tests for people with acute clinical need and those in social care settings as he acknowledged "operational challenges" in the system.
The updated prioritisation list which will set out who will be at the front of the queue is yet to be published.
Mr Gething said he was not keen on implementing the rationing of tests in Wales, but said he could not rule it out at this stage if problems in the system continued.
