1. What this policy covers

This policy applies to BloodSight's educational reference library — our biomarker pages, panel pages, learning guides, and blog.

2. Who writes our content

Reference content is researched and written by the BloodSight Editorial Team. Pages are written for the person reading their own lab results — not as clinical guidance — and every page is built directly from the primary sources described below rather than rewritten from other consumer health sites.

3. How we source information

We build content only on primary, authoritative medical sources. In order of preference:

• U.S. National Institutes of Health and its institutes — including NIDDK, NHLBI, and the Office of Dietary Supplements.
• MedlinePlus, the consumer service of the U.S. National Library of Medicine.
• The World Health Organization and its published guidelines.
• Recognized specialty societies — such as the American Thyroid Association, American Heart Association, American Diabetes Association, and National Kidney Foundation — for guideline-level statements.

Each reference page cites the specific sources it relies on, and at least two of those are drawn from the NIH family or the WHO. We do not treat consumer health publishers, competitor sites, or crowd-edited encyclopedias as authorities for the facts on our pages. Links to sources are verified at publication; a dead or redirected link is replaced, not kept.

4. Accuracy and attribution

Two principles govern everything we publish:

• We describe and attribute, we never prescribe. We explain what a marker measures and what high or low values can indicate. We do not tell you what to do about your results — that is a conversation for you and your clinician.
• Numbers carry their source. Reference ranges, thresholds, and cutoffs are attributed to the authority they come from, because laboratories, populations, and guidelines differ. Your own lab's reference range always takes precedence over any general figure on our pages.

5. Review and updates

Before publication, every page is checked against its cited sources for factual accuracy and reviewed for clarity. Each reference page carries a last-updated date, and we revisit pages as the underlying medical guidance changes or when readers flag an issue. When we make a material change to a page, we update its date.

6. Editorial independence

Our reference content is editorially independent. It is not written, edited, or approved by advertisers or sponsors, and we do not accept payment to feature, omit, or frame any biomarker, test, or treatment in a particular way.

7. Corrections

If you spot an error, an outdated figure, or a broken source link, please tell us. Email support@bloodsight.com with the page and the issue, and we will investigate and correct it. You can reach us through our contact details as well.
