Get in touch
One address, read by the people who maintain the site. There is no form to fill in and no ticketing system.
Corrections are prioritised, because a wrong number on a medical page is worse than a missing feature.
A correction
A number, cut-point, citation or sentence on this site is wrong. Include the page, the exact claim, and the source you would cite instead. Corrections are applied with a note in the page’s references.
A clinical review
This site wants named clinical review of its content. If you are a clinician with lipid expertise and would be willing to review a page, write with your name, role and registration so it can be credited properly.
A bug
The calculator produced something that looks wrong, or a page is broken on your device. Include the three values you entered, the unit, the browser, and — if you have it — the permalink from the address bar.
Something else
Translations, accessibility problems, or a feature that would make the calculator more useful. Practical suggestions are read before feature requests.
What this address cannot do
It cannot give medical advice. The site has no clinical staff, cannot see your history, and will not interpret your results, comment on a dose, or tell you whether a value is dangerous. That is not a legalistic dodge — it is the difference between a reference table and a consultation, and it is set out in full on the medical disclaimer page.
If you have chest pain, breathlessness, or symptoms that worry you, contact emergency services or a local urgent care service rather than this site.
