Specific thresholds for ferritin are used to detect iron deficiency and overload in different age groups. The World Health Organization (WHO) estimates that 42% of children less than 5 years of age and 40% of pregnant women worldwide are anaemic.
9 Δεκ 2023 · In terms of screening recommendations, five guidelines recommend screening with ferritin in addition to a full blood count in pregnancy, two recommend selective screening with ferritin for at risk groups only, and one guideline suggests using ferritin where feasible.

23 Φεβ 2017 · Ferritin reflects total body iron stores. Iron deficiency is the only clinical situation associated with extremely low values of ferritin. Ferritin declines gradually during pregnancy, reaches a nadir during weeks 35 to 38, and increases during the month before delivery.
