How we research, write, review, and maintain every piece of medical content on MedicalToolKit.
MedicalToolKit is committed to providing health information that is accurate, evidence-based, and easy to understand. Every calculator, formula, and article on this site is built on clinically validated sources — never guesswork, never AI-generated medical claims without verification, and never information that contradicts established medical consensus. We hold ourselves to the same standard we'd want for our own family's health decisions.
Every calculator formula and health claim is sourced from peer-reviewed journals, official guidelines (WHO, CDC, ADA, AHA, ACOG), or established clinical references like the Mifflin-St Jeor equation or Naegele's Rule.
Before any calculator goes live, we test the underlying formula against published reference values and known clinical examples to confirm mathematical accuracy across edge cases (extreme heights, weights, ages).
Educational content is written to be clear and actionable while remaining faithful to the underlying science — no oversimplification that changes meaning, and no sensationalized claims to drive clicks.
Content is checked against current clinical guidelines before publishing. Where guidelines differ by organization (e.g., AHA vs. ESC blood pressure thresholds), we note the discrepancy rather than picking one silently.
Medical guidelines evolve. When major organizations update their recommendations (e.g., 2017 AHA blood pressure guideline revision), we review and update affected pages. Every article displays its last-reviewed date.
We prioritize information from the following types of sources, in order of preference:
We avoid relying on unreviewed blog posts, forums, or single anecdotal sources for any clinical claim. Every blog article on our site includes a References section listing the specific sources used.
MedicalToolKit is an educational and screening tool — not a substitute for professional medical care. Our calculators provide estimates based on validated formulas, but only a licensed healthcare provider can diagnose conditions, interpret your specific results in context, or prescribe treatment.
If any calculator result concerns you, or if you're experiencing symptoms, please consult a doctor. Our full Medical Disclaimer is available here.
We take accuracy seriously. If you believe any content on MedicalToolKit contains an error — whether a calculation issue, an outdated guideline reference, or a factual mistake — please contact us immediately. We review every report and issue corrections promptly, noting the update date on the affected page.
We're happy to explain our sourcing for any specific calculator or article.
