Question to the Department of Health and Social Care:

To ask Her Majesty's Government how many COVID-19 home tests returned to them were not viable owing to difficulties in collecting a sample of the virus when self-swabbing.

International peer reviewed evidence, as well as the National Testing Programme’s experience, is that void rates for self-administered tests are of a similar level to clinician-administered tests. The best international evidence, as well as the Programme’s internal data, are kept under constant review, and significant resource has been deployed to ensuring that the instructions for self-administration are clear and easy to follow.
