Needs a look Ferritin Draft · pending review

Ferritin 11 ug/L on 2026-11-12 09:05 meets the published definition's criteria for the category “band below the ferritin cut-off for this group” (who2020_iron_deficiency_ferritin@1.0). The note doesn't mention this.

Published bodies disagree on these thresholds; another definition may give a different answer.
