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

*An indeterminate test result means that the laboratory could not obtain a valid result from the swab sample and so were unable to determine whether SARS-CoV-2 virus was present. This may occur because of a number of technical reasons. Following an indeterminate result, it is recommended that the individual be retested.
