Accessibility

We want this site to be usable by everyone who needs it, including people using screen readers, keyboard navigation, magnification or high contrast settings. Many of the people this site is built for are unwell, exhausted, or reading on a phone in a hospital corridor. Accessibility is not a nice to have here.

This page says what we have actually checked, and what we do not claim.

What we have checked

  • Semantic HTML. Pages are built from real headings, lists, links and landmarks rather than styled containers, so assistive technology can navigate the structure.
  • Skip to main content. Every page opens with a skip link, so anyone navigating by keyboard or switch can jump straight past the header and navigation instead of tabbing through them on every page.
  • Colour contrast. Text meets the 4.5 to 1 contrast threshold against its background. This was last measured on 17 September 2026 across thirty foreground and background pairs, computed from the stylesheet the site actually ships, with no failures.
  • Links you can see without relying on colour. Links inside body text are underlined, so they are distinguishable to readers who cannot easily tell the colours apart.
  • Keyboard navigation. The site works without a mouse.
  • Motion. Nothing autoplays and nothing flashes. The few things that do move are a loading indicator and two small entrance animations, and if your device is set to reduce motion they do not run.
  • Automated testing. We run the axe accessibility scanner against a set of representative pages every week, including the pages with forms and with results rendered in the browser, and we keep a dated report of every run.

What we do not claim

We do not claim conformance with WCAG at any level, and you should be sceptical of any site that claims it without publishing evidence.

Automated scanning catches roughly a third of real accessibility problems. A clean automated report means our automated checks pass. It does not mean the site is free of accessibility problems, and we are not going to present it as though it did.

We have not commissioned an independent audit, and we have not done systematic testing with real users of assistive technology. Until we have, a conformance claim would be a marketing statement rather than a factual one.

If something does not work for you

Tell us and we will fix it. Use the "Report an issue" link on any trial, condition or medicine page, or the contact page. Describe what you were trying to do and what got in the way, and if you can, tell us what you were using: the browser, the device, and the screen reader or other assistive technology. That is usually the difference between a report we can reproduce and one we cannot.

We read every report and reply as soon as we can. If a page on this site is the barrier between you and information about your own health, that is our problem to solve, not yours to work around.
