Accessibility statement

Health Decoder is committed to making blood-test education usable by the widest possible audience, including people using assistive technology and people with situational or permanent disabilities.

Conformance target

We target WCAG 2.2 Level AA. Each substantive content or design change is checked with automated tooling (axe-core, Pa11y, Lighthouse) in both light and dark color schemes before it ships.

What we test

• Keyboard-only navigation on every interactive element
• Color contrast ≥ 4.5:1 for normal text and ≥ 3:1 for large text and non-text UI, measured in both light and dark themes
• Screen-reader semantics — heading hierarchy, landmarks, descriptive link text, form labels, skip-to-content link
• Respect for prefers-reduced-motion and prefers-color-scheme
• Mobile tap targets ≥ 24 CSS pixels per WCAG 2.2

Known limitations

Automated testing catches roughly 20–50% of accessibility issues. The following items are known work-in-progress; if you hit any of them, please tell us.

• Some WCAG 2.2 target-size warnings on the primary navigation and skip-link are being evaluated — the tap areas meet the minimum on touch devices but can appear dense on desktop.
• Interactive components added by third-party integrations (e.g. embedded checkout) use their providers' accessibility conformance; we audit around them but cannot fully control them.

Report an accessibility issue

If something on this site is hard to use with assistive technology or doesn't meet the target above, email support@decoder.health with the page URL, the device/browser/AT combination, and a brief description. We aim to respond within five business days.
