Adding this field to a basket will grant access to the covid19_result_england, covid19_result_scotland and covid19_result_wales tables on the Data Portal. If included, the field will also appear in a main UK Biobank dataset where it will give a count of the number of rows for each participant across these three tables.
For usage guidance and further details on the COVID-19 test results data, please see the COVID-19 test result page on Essential Information. Details of the structure of the above tables as well as the meaning of the encoded values used can be found by downloading the Covid-19 test result data dictionary.
More details on linkage of microbiological samples to the UK Biobank are available at http://www.bugbank.uk/. Please also see Resource 1758 for more detail about the PHE linkage for the English data.
Please note that prior to 6th July 2021, a small proportion (6.5%) of the records in the covid19_result_scotland table related to lateral flow device testing. These records have been removed and all data in this table now relate to PCR testing.
