question text	To ask Her Majesty's Government, further to the Written Answer by Lord Bethell on 10 December (HL10848), what steps they have taken reliably to determine the operational false positive rate for polymerase chain reaction COVID-19 mass testing; and how they have made any such determination.

uin	HL11385
answer	answer is ministerial correction date of answer 01/02/2021 answer text <p>Polymerase chain reaction tests are very specific and the risk of false positives where the test is reacting to other viruses is extremely low. Independent confirmatory testing of positive samples indicates a test specificity that exceeds 99.3%, or a false positive rate of 1%, and additional guidance has been provided to laboratories to reduce the rate even further.</p> answering member printed Lord Bethell question first answered 01/02/2021 12:33:47 answering member 4708 label Biography information for Lord Bethell

question text	To ask Her Majesty's Government, further to the Written Answer by Lord Bethell on 10 December (HL10847), whether they will now answer the question put, namely, whether the operational false positive rate for polymerase chain reaction COVID-19 tests is regularly determined by inserting samples into the system that cannot be positive; and what is the false positive rate for such samples.

uin	HL11386
answer	answer is ministerial correction date of answer 16/03/2021 answer text <p>Information regarding the assessment of false positives was not held in the format requested due to the challenges in estimating clinical sensitivity. This is part due to a lack of a generally accepted reference standard to compare reverse transcription polymerase chain reaction results. <br> <br> Currently samples are not placed into the system to test operational sensitivity. The Department has undertaken substantial work with Porton Down and the Milton Keynes Lighthouse Laboratory to conduct temperature and long-term stability experiments on sample collection kits to ensure swabs meet an appropriate standard for testing.</p> answering member printed Lord Bethell question first answered 16/03/2021 17:02:43 answering member 4708 label Biography information for Lord Bethell
