How we identify participants for the NHS-Galleri Trial

Find out how we invite participants to take part in the NHS-Galleri Trial and how to opt-out if you do not wish to take part.

A new test has been developed that can detect many types of cancer from a single blood sample, called the Galleri™ test.

The NHS-Galleri Trial is a research trial to see how well the new Galleri™ test works in the NHS. The aim is to see whether the test finds cancer earlier when combined with standard cancer testing in people who don’t have any symptoms of cancer.

You can learn more about the test, the trial and who is eligible to take part on the NHS-Galleri Trial website.

The trial will invite a number of eligible participants from around the country - you do not need to volunteer.

If you do not wish to take part, you can opt out of being invited below.

How NHS Digital uses your information

NHS Digital has been asked to identify potentially eligible participants and to invite them to join the NHS-Galleri Trial. We will use the data we hold to identify suitable people and to send them an invitation to participate in the trial. The data used will include name, date of birth, address, NHS number and information about cancer diagnosis. Your personal data will not be shared directly with the trial.

If you decide to take part in the trial, you will be asked to provide written consent to the trial at your first visit.

If you have requested that your NHS data is not shared for research and planning purposes (by registering a National Data Opt-out) then you will not receive an invitation for this trial.

The trial has requested that all potentially eligible participants be contacted once only. To manage the invitation process, we will need to keep the trial invitation list until six months after the trial recruitment in completed. This is to ensure that you are not invited again and that those who have told us that they do not want to be contacted, do not receive an invitation in the first place.

After that, all the information stored for the purpose of this trial will be deleted. You can find out more about your choices on how the NHS uses your data for research and planning.

We will use your data to produce summary reports to monitor recruitment into the trial (for example how many people were invited). These reports will not identify you personally.

The Health Research Authority has provided legal support to the NHS-Galleri Trial under section 251 of the National Health Service Act 2006 – this includes permission for NHS Digital to process data on behalf of the trial. This support provides the legal basis for suitable participants to be identified and invited to join the trial. This is following advice from the Confidentiality Advisory Group, an advisory body which provides independent expert advice on the use of confidential patient information without consent in England and Wales.
