Reply from DH re LFT Legislation16 Oct 2021 12:12
I wrote to my MP in July re the proposed legislation regarding LFTs and their authorisation. I have just received this reply for what it is worth sent in two Parts :
Part 1
"Alongside the symptomatic testing service, NHS Test and Trace is using rapid-testing technologies for asymptomatic individuals and to improve our detection of positive cases. Roughly one in three people who have the virus do not have symptoms and could therefore be spreading the disease without knowing it.
The process of deploying a lateral flow device (LFD) test, such as those supplied by Innova and Orient Gene, into the mass-testing programme is robust, consisting of detailed validation and evaluation of the LFD prior to deployment. LFD tests have been rigorously tested and are safe for regular use; any suggestion otherwise is inaccurate and potentially harmful.
All LFD tests that we procure undergo an extensive clinical evaluation by Oxford University and Public Health England (PHE) Porton Down. This is to confirm that the LFD tests display performance characteristics desirable for mass-population and community-based testing. The desirable performance characteristics are high specificity and sensitivity against the viral loads associated with infectiousness, and the work performed at PHE Porton Down assesses the clinical performance of LFD tests.
We applied to the Medicines and Healthcare products Regulatory Agency (MHRA) for an ‘exceptional-use authorisation’ for the Innova LFD, and Orient Gene independently applied. The MHRA provided the exceptional-use authorisations to fill short-term gaps in the market, as no CE-marked self-tests were available. Both devices have subsequently been deployed in the UK, with the exceptional-use authorisations providing the regulatory authority for deployment.
The process of applying for an exceptional-use authorisation requires the applicant to provide data to support the intended use of the LFD test. In these instances, we, on behalf of Innova, and Orient Gene provided the MHRA with data in support of applications for LFD tests that use a lower nasal swab and are intended for use on asymptomatic
individuals. Furthermore, we conducted field-service evaluations before deciding to deploy the LFD tests. The results of the field-service evaluations can be found at www.gov.uk/government/publications/lateral-flow-device-performance-data."
