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.
