The Welsh Government is leading a consortium of stakeholders within Wales to deliver our national plan for COVID-19 testing. Details of the plan which has been in place since 28 March.

Our national testing plan has two main aims:

  1. to reduce the harm caused by coronavirus
  2. to help the public and professionals get back to their normal daily lives

On 15 April, the Health Minister commissioned a rapid review of the testing regime to identify where improvements could and should be made. These are all recommendations of a review ordered by the Health Minister following concerns that not enough tests were being carried out under the current system.

Who gets tested

Our current phase of activity of the testing plan is focussed on our critical workers, symptomatic patients in hospital and care homes.

In Wales, there are 483,000 critical workers; this includes 168,500 Healthcare workers, 9,900 police and prison staff. The broad categories of Critical Workers includes:

  • health and social care workers
  • public safety (emergency workers) and national security workers
  • local and national government workers
  • education and childcare workers
  • food and other necessary goods
  • transport
  • utilities, communication and financial services workers
  • key public service workers

This week, the daily testing capacity at the laboratory increased to 5,330. Two new drive through testing centres opened, the first in Swansea opened on Wednesday, 6 May and was followed by another in Abercynon on Thursday, 7 May.  These complement the testing centres already open in Cardiff, Newport, Llandudno and Carmarthen. We also have eight mobile units operational across Wales, which will increase the capacity and reach available.

Testing is being prioritised for health and social care workers, police, fire services and prison workers. We are increasing Wales’ testing programme for all groups of critical workers, to provide greater reach and flexibility. We are continuing to work with partners to develop an online portal. Further information outlining the testing process and how to book a test is available on the Welsh Government website and will be updated regularly as the process develops.

We have established a three-stage testing and rapid response package, which is being introduced to help protect care home residents and staff. This does not rely on testing alone. This includes making it easier to get a test done, targeted testing on outbreak hot spots and providing environmental and hygiene support. Further information can be found on the Welsh Government website.
