Who developed the Galleri test?

The Galleri test was developed by researchers at GRAIL, LLC in the US. Results from trials using the Galleri test suggest that the test can work well. The NHS now wants to do further work to understand whether the test works well enough to routinely offer it to people in the UK in the future. 

Is anyone else involved?

GRAIL collaborates with patients and the public to make sure that information for participants in the NHS-Galleri trial is clear and understandable.

The trial uses the services of third-party organisations in the UK and outside the UK to help run the trial. They may handle information about people taking part in the trial. They will be required to do this safely and securely.
