- If you find an error, tell us. We review every report.
- Factual errors that could affect health decisions are fixed as quickly as possible once confirmed.
- Significant corrections are noted at the end of the article with the date and what changed.
We work hard to be accurate, but mistakes can happen and medical guidance changes. This policy explains how to report a problem and what we do about it.
How to report an error
Use our contact form and include:
- The page address (URL) and the sentence, number or graphic in question
- What you believe is wrong
- A source, if you have one (a guideline, paper or official page)
What happens next
We acknowledge it and go back to the original sources.
We correct it immediately once confirmed, for example a wrong test threshold, a safety warning or a medicine fact.
We fix typos, broken links and small wording issues in our next update.
We reply with the sources we relied on. If the evidence is genuinely mixed, we may update the article to say so.
How corrections are shown
| Type of change | How we show it |
|---|---|
| Significant correction (a fact, number or recommendation was wrong) | A dated “Correction” note at the end of the article saying what changed |
| Update (new guideline or evidence) | The “Last reviewed” date is updated; major updates are summarized in a note |
| Minor fix (typo, link, formatting) | Fixed without a note |
We cannot give personal medical advice. If your question is about your own results or treatment, please talk to your doctor. For urgent symptoms, seek emergency care.
