Range Atlas is AI-collected and not medically reviewed. It is for informational purposes only, meant to help curious people start a conversation with a healthcare professional. The chart shows how sources disagree, not whether a value is good or bad for you. Color shows what each source's region means, not a recommendation.

Ferritin in ng/mL (equals ug/L). Ranges are strongly sex-specific and the male upper limit (often 500+) is above this axis, which focuses on deficiency and optimization thresholds.
Unit rule: normalize to common United States display units. Mayo is the tiebreaker, then Quest, then Labcorp. Fixture: 17 markers, 101 rows, 70 source names, 11 conversion rules.
visualShape is stored geometry (band, floor, ceiling, point). regionMeaning is stored polarity (reference, optimal, concern_low, concern_high). Neither is inferred from labels at render time.
No marker-specific conversion rule is needed for this selected fixture row set.
