Accessibility Statement

We have undertaken to use our knowledge and understanding of the ways in which different people access the Internet to develop a website that is clear and simple for everybody to use.


We have used HTML5 and CSS that conform to specification, as laid out by the W3C, because we believe that usability and accessibility must have a solid foundation built upon web standards. If anything on this website does not validate correctly, please contact the LOINC team.

We have also endeavored to achieve AA accessibility as measured against version 2.0 of the WCAG. We are aware however, that a number of the checkpoints of the WCAG are subjective—and although we are sure that we have met them squarely, there may be instances where interpretation may vary.
