General description

Data collection and calculation

The data is management information which has been collected to support testing operations. We’re publishing these data to provide a timely summary of testing activity but they have not undergone the same level of quality assurance as official statistics, with the data subject to future revisions.

Frequency of publication

Weekly

Data reference periods

18 May 2020 onwards

Revisions information

The data are management information, not official statistics, and are revised regularly. The Public Health Wales surveillance dashboard is updated daily with the most recent data, including revisions to the data published here.

From 13 July 2020, Public Health Wales have combined tests and results processed in NHS Wales laboratories and non-NHS Wales laboratories, which were previously reported separately. Further details are included in the release outlining which tables and charts show tests authorised for both laboratories or separately. The data has been revised historically except for the annex table showing the number of tests authorised in the last 24 hours to 1pm, which reflects what was published on the Public Health Wales surveillance dashboard on a given day.

On the evening of Friday 11 December 2020, there was planned maintenance of the Welsh Laboratory Information Management System (WLIMS) to allow essential service upgrades to take place. On Monday 14 December 2020, figures were updated for the period of 1pm on Friday 11 to 9am on Sunday 13, a total of 44 hours, however the data flows for tests from the WLIMS had been affected during this period. After this downtime, there was a period of data reconciliation and validation which are reflected in the figures in this publication.

Statistical quality

The total number of tests completed may differ to other tables due to different reporting times. For the purposes of this analysis, a week is classed as 00:00 Monday to 23:59 Sunday.

The number of tests and results reflect a snapshot in time and will be greatly influenced by the sampling strategy at that moment in time. More information is available in the Antibody testing: coronavirus (COVID-19) pages of our website.

If an antibody test is equivocal, it means that the result is inconclusive.

Prior to December 2020 antibody tests were conducted by local health boards in Wales for surveillance of key groups working in health, social care and education. The testing of domiciliary care workers continued until April 2021. Antibody tests taken for diagnostic reasons in hospital settings are also included in the data presented in this release.
We won’t be revising data past 52 weeks.
