Blood test values you enter
MyLabRanges performs its result comparisons in your browser using JavaScript. The blood test values and reference ranges you enter into the checker are not uploaded to, or stored by, MyLabRanges on a server.
If you close or refresh the page, the site does not provide an account or server-side record from which those entered values can be retrieved.
Website analytics
MyLabRanges uses Cloudflare Web Analytics to understand basic site usage and performance, such as page views and page-loading performance. Cloudflare describes Web Analytics as privacy-first and states that it does not collect or use visitors’ personal data or track individual users across customers’ websites.
The analytics beacon does not read the blood test values entered into the MyLabRanges form.
Cookies and advertising
MyLabRanges does not currently serve third-party advertising.
If advertising is introduced in the future, this Privacy Policy will be updated before or alongside that change. Where required, an appropriate consent-management mechanism will be provided for technologies used for advertising, cookies, local storage or personalised advertising.
External links
The site links to external sources such as NHS information pages. Those websites operate under their own privacy policies and terms. MyLabRanges is not responsible for the privacy practices of external websites.
Changes to this policy
This policy may be updated as the site develops, particularly if new analytics, advertising or other third-party services are introduced.
