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

Last week, the daily testing capacity at the laboratory increased to 2,100.  Work to increase this capacity will continue and we expect to significantly add to this number over the coming weeks.

Two new drive through testing centres opened, the first in North Wales opened on Wednesday, 29 April and was followed by another on showground site in Carmarthen on Thursday, 30 April.  These complement the testing centres already open in Cardiff and Newport.

At present testing is being prioritised for health and social care workers, police, fire services and prison workers. This is to ensure essential core services can continue. The objective is to increase and improve Wales’ testing programme for all groups of critical workers as soon as possible, to provide greater reach and flexibility.

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.

A new web-based booking system is now available for a priority list of major employers to be able to refer symptomatic critical workers (including a symptomatic household member of a critical worker not showing symptoms) in South East Wales, to book a test at the Cardiff and Newport mass drive-through testing centres.

For the other regions of Wales, there will be a brief transition from manual to web-based bookings through the new drive-through centres in South West and North Wales and the aim will be to roll this out as quickly as possible.
