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.

TSH in mIU/L (equals uIU/mL). Lab reference intervals are wide; some bodies and practitioners argue for a narrower upper limit.
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.
