Symptom Checker App

The right care at the right time


Our app is automatically tested (structure, markup) and manually tested for accessibility (keyboard navigation, screen reader support).

Our app is reviewed for compliance with WCAG 2.0 and a11y guidelines for accessibility.

WCAG 2.0

Our app is compliant with WCAG 2.0 checklist Level AAA (Advanced).

The symptom checker app is compliant with the guidelines, but it is possible that you could break compliance with 1.4.1 – Use of Colour (Level A) by providing a bootstrap theme that does not follow the guidelines.

Here are some helpful resources:


Our symptom checker app depends on the use of javascript and requires javascript to be enabled. With the exception of the javascript section, the symptom checker app can be compliant with the Web Accessibility Checklist. It is possible to break compliance by using colors with insufficient contrast in your bootstrap 4 theme.

When designing your theme, consider the following guidelines:

The A11Y guidelines discourage the use of inline scripts. Our embed script includes a short inline script. We recommend this because it simplifies implementation and keeps the implementation details for our application grouped together on the host page. If you are concerned with this recommendation, please move this part of the embed script to a local javascript file.
