​Please can you provide the entire data set of all positive cases and deaths with the Cycle Threshold added.

This is the number of times the sample is amplified before it gives a positive result.

We said

Thank you for your request.

Due to Statistical Disclosure Control, we would not be able to publish the full data set of threshold cycles for each positive case, as this would constitute personal data. Section 39 of the Statistics and Registration Service Act 2007 (SRSA) renders it an offence to disclose information held by the Statistics Board for statistical purposes that would identify an individual. As we are prohibited by law from publishing statistics in which individuals can be identified, we find that Section 44 of the Freedom of Information Act 2000 (FOIA) applies. Section 44 is an absolute exemption and no consideration of the public interest test needs to be applied.

However, this can be accessed through our Secure Research Environment, if you have the correct permissions. You can find information on this here.

Please also see the following information relating to your request, which may be of interest:

We have not found any sample which has been positive with a CT Value above 37, with the exception of one.

To clarify, our data is from the community population of England. We test a random sample of the population and, therefore, our positive cases include those who are and are not symptomatic.

Our academic partner at the University of Oxford has been producing Threshold Cycle analysis. They plan to publish a paper on this later this year.

We have also not yet linked information about deaths to our dataset.
