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

The daily laboratory testing capacity currently stands at 9,277 and we will continue to increase this capacity over the coming weeks as we now move to mass population testing to support contact tracing. To scale up the approach to testing, an extensive network of testing facilities is now in place with mass drive-through testing centres fully operational in Cardiff, Newport, Swansea, Abercynon, Carmarthen and Llandudno, 8 mobile testing units and a network of Community Testing Units (CTUs) across Wales.

Anyone in Wales who has symptoms (a new continuous cough OR fever OR loss of smell or taste) is now eligible to apply for a home testing kit or a slot at a mass drive-through centre in Wales through the UK public testing website. Daily allocations of tests will be prioritised for critical workers initially where demand outstrips supply. 

Another type of test is now available – this is the antibody test. This tests a blood sample to see whether someone has been exposed to coronavirus infection and has developed antibodies – has some immunity to the virus. Policy outlining how this type of test will be used in Wales will be published shortly.

People living in care homes and other similar residential settings are amongst the most vulnerable to COVID-19 so large scale implementation of testing in care homes is vital to preventing and managing outbreaks. Every care home in Wales can access testing for residents and staff. Local Health Boards are managing testing arrangements locally, which includes access to home testing kits through a dedicated care home portal. Read more information on our care home testing policy.

We published our Test, Trace, Protect strategy on 13 May which will help us live and work alongside the virus while research continues to find more effective treatments and a vaccine. Four local authorities have been piloting the contact tracing system, which we launched nationwide on 1 June.
