How we write and review pages

What we cover, and what we don’t

We explain what laboratory results commonly mean, how markers relate to one another, and what clinicians usually check next. We do not diagnose, recommend doses, or suggest starting or stopping any treatment. When a result pattern is usually followed up promptly, we say so plainly at the top of the relevant section.

Sources

Every clinical claim is based on primary sources: guidelines from bodies such as the World Health Organization, national gastroenterology and hematology societies, the NIH Office of Dietary Supplements, and peer-reviewed research. Sources are listed at the foot of each page. We don’t cite other consumer health websites as evidence.

Review

Every page with clinical content is reviewed by Gunda Grüttner, Licensed Nurse (Krankenschwester, Germany), before publication. The reviewer checks each threshold against its source and can block publication. A page shows the date it was last reviewed; a page that hasn’t been reviewed says so and is not offered to search engines.

Our reviewer is a nurse rather than a physician or dietitian. That is why our pages stay within patient education — explaining results and preparing you for a conversation with your clinician — rather than clinical decision-making.

Reference ranges

Laboratories print different ranges for the same test. Where we give numbers, we distinguish between a lab’s reference range and a clinical threshold, and we always tell you to read your result against the range on your own report.

Updates and corrections

Pages are re-checked at least once a year, and whenever a major guideline changes. If you find an error, email info@micronutrienttest.com. Substantive corrections are noted on the page with the date.

Independence

How the site is funded never decides what a page says. See how we make money.
