Dr Julian Lewis: To ask the Secretary of State for Health and Social Care, what recent estimate the Government has made of the level of risk of incorrect negative covid-19 test results due to ineffective application of swabs to the (a) throat and (b) nose; and what steps the Government is taking to reduce that risk. 
[Due for Answer on 2 June. Answered on 14 September – over 3 months late.]
HOLDING ANSWER: The Department of Health and Social Care has indicated that it will not be possible to answer this question within the usual time period. An answer is being prepared and will be provided as soon as it is available.
The Minister of State for Social Care (Helen Whately): International peer reviewed evidence, and real-world assessments from the Department’s testing programme has shown that swab tests taken by non-clinically trained individuals are just as effective as those taken by clinicians. The Department has clear guidance included with all self testing swab kits and material on GOV.uk and a video guide on Youtube detailing the process of self-swabbing.
