PCR Test Amplication

We're waiting for Barbara Jones to read a recent response and update the status.

Dear Public Health England,

What limits on amplication on the PCR test does England use and/or recommend?
Please send me any directive or letter authorising this.

Yours faithfully,

Barbara Jones

Dear Barbara Jones,

We acknowledge receipt of your email and request for information, which will be treated as a request for information under statutory access legislation.

Please note that requests under the Freedom of Information Act and the Environmental Information Regulations (EIRs) will receive a response within 20 working days from the day following the date of receipt of your request.

If the request is for your personal data, your request has been handled as a data subject access request (SAR) under Article 15 of the General Data Protection Regulation (GDPR), then we will respond within one month of the receipt of the request.

Public Health England (PHE) is responsible for providing guidance and advice to government and front-line services for all aspects of public health. It is a designated Category 1 responder organisation under the Civil Contingency Act and this specifically includes the COVID-19 response, providing clinical expertise and wider public health advice and guidance across national and local government, the NHS and third sector. As such, you may experience delays when making statutory information access requests during the pandemic.

We will aim to address all requests promptly and within the required response timeframes. However when we are unable to meet the response timeframe we will keep requesters updated on a revised expected timescale for a response to their request. The Information Commissioner recognises this position in its recent guidance, see link: https://ico.org.uk/global/data-protectio...

Dear FOI,
Thankyou for your answer, which appears to be a copy of someone elses reply, and not directly a reply to my questions.
"Please could you tell me which organisation decides how many times the PCR (polymerase chain reaction) tests are amplified?2. How many times are the PCR tests are amplified in England?"

To clarify, please could you tell me if PHE gives any guidance whatsoever on the number of times the PCR tests are amplified?

"Laboratories have a statutory duty to report positive cases to PHE, but they are not obliged to advise PHE which tests they are using nor submit CT values used to PHE. "
This appears lax to the point of negligence, as the number of times amplification affects the positivity rate. Can you confirm that PHE chooses not to oblige the labs to advise the number of amplification cycles?

Can you tell me if the labs are obliged to answer FOI questions as they are doing government work which is is of obvious public interest?
Please tell me what a "gene target" is and give an example.
Please give me a copy of the directive/order from PHE or that the labs must tell PHE when they produce a positive covid result. If there is a postive result, is there a payment made to the lab?

Yours sincerely,

Barbara Jones

Dear Barbara Jones,

There are many different assays in use across the United Kingdom within the UK Government mass testing programme and within commercial laboratories.

Under section 16, a public authority has a duty to provide advice and assistance. Accordingly, you may wish to contact the Department of Health and Social Care (DHSC), which holds overall responsibility for the UK government mass testing programme and may be able to advise on assays used in non-PHE laboratories. For further information on the exact sequences, you may wish to contact the commercial manufacturers of the assays for further information.

PHE uses a number of assays within its laboratories, many of which are commercial assays and use a variety of gene targets, usually two or more in a single assay; including the n (nucleocapsid), e (envelope), orf 1 ab and s(spike) gene.

You may be interested in the collection 'COVID-19: PHE assessment of laboratory tests and assays', which provides information, resources and guidance relating to the evaluation of COVID-19 tests. This includes the specific genetic targets for the assays being evaluated. You can access information on PHE's work in this area at:
https://www.gov.uk/government/collection...

Please note, PHE evaluation is not mandatory for COVID-19 diagnostic tests and assays. PHE evaluates tests to inform the choice of tests in our own laboratories and at the request of the Government to support partners in their testing work on COVID-19 and inform potential procurement decisions.

Yours sincerely,
