Accessibility statement

This accessibility statement applies to the NHS-Galleri Trial website (

It’s important that as many people as possible are able to use this website. As such we have tried to make the site accessible for those who may need to use assistive technologies or have other accessibility requirements, as well as making the content as simple as possible to understand.

We are continually evaluating and improving the website’s accessibility performance against the Web Content Accessibility Guidelines (WCAG) Level AA standard.

Below are some of the steps that have been taken towards greater accessibility.


  • The website’s design uses a clear typeface in legible font sizes at appropriate colour contrast ratios.
  • Text on the website can be increased without assistive technology up to 400% without loss of content or functionality. In modern browsers, you can change the font size of a website by holding Ctrl’ on Windows or Command’ on Mac, and pressing ‘+’ to increase or ‘-’ to decrease the font size.
  • Links have been given appropriate colour and underline differentiation from non-interactive text, as well as being written to make sense out of context.

Keyboard navigation

  • You should be able to navigate most of the website using just a keyboard.
  • A high-visibility focus state has been added to certain elements to help keyboard users identify where their current focus is.

Screen reader compatibility

  • This website uses semantic HTML – including appropriate ARIA roles and attributes – to help screen readers understand the page.
  • Additional information may sometimes be visually hidden but conveyed exclusively to screen readers where the context is inherently visible (e.g. graphs of data).
  • The site has been tested with VoiceOver on Mac, Narrator on Windows and NVDA screen reader.
  • Where appropriate, descriptive alt text attributes have been added to images.

PDF files

Some content, such as the Participant information sheet, have been provided in PDF format. As authors of these documents, we have tried to make them as accessible to screen reader software as possible but acknowledge this may not always be possible.
