¹As documented in the data sharing agreement.
²As explained in the Department of Health and Social Care’s (DHSC) COVID-19 Scaling up our testing programmes four pillars comprised the UK government’s approach to testing for SARS-CoV-2.
Pillar 1 quantified the number of people with a clinical need, and health and care workers, who returned positive swab (antigen) tests (processed in PHE labs and NHS hospitals).
Pillar 2 quantified the number of people in the wider community who returned positive swab (antigen) tests (processed in commercial labs).
Pillar 3 quantified the number of people who returned positive serology (antibody) tests to detect immunity and to understand the efficacy of the different testing methods.
Pillar 4 quantified the number of people who returned positive serology (antibody) and swab (antigen) tests to detect immunity and to understand the efficacy of the different testing methods.
