Question to the Department of Health and Social Care:

To ask His Majesty's Government when antibody testing in the UK to determine the cohort most at risk from COVID-19 will be introduced; and what assessment they have made of the testing level of <264 BAU/ml set by the government of France in early 2022 to define its at risk group for COVID-19.

The Department has received an application from a research team to lead a study to establish if antibody testing can identify which immunosuppressed individuals remain at greatest risk of severe COVID-19 infection after vaccinations, and if possible, define testing thresholds for COVID-19 risk. This will aim to improve the understanding of COVID-19 risk in immunosuppressed individuals to inform future advice. We are currently working with the National Institute for Health and Care Research to assess the study proposal. Further information will be provided when details are available.

We have made no assessment of the antibody testing threshold level set by the French Government.
