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.
This field will also grant access to table covid19_misc in the Data Portal. This table gives participants' blood group extracted from imputed genotyped data (Field 23165) and was added in July 2020 as a result of the suggestion that blood group may affect COVID-19 outcomes.
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.
