Common mistakes around Ferritin Kinder

Common mistakes around ferritin in children: First, ferritin is often misinterpreted as a standalone marker for iron deficiency. Ferritin is an acute-phase reactant and can be elevated during infections, inflammation, or chronic disease, even when iron stores are low. Second, low ferritin does not always mean iron deficiency – it can also result from hypothyroidism, vitamin C deficiency, or poor dietary intake. Third, iron supplementation is often started prematurely without proper diagnosis. Iron overdose is toxic, especially in children, and can cause liver damage. Fourth, age- and sex-specific reference ranges are ignored – infants and toddlers naturally have lower ferritin levels. Fifth, ferritin is used in isolation without measuring transferrin saturation, hemoglobin, or CRP. A complete iron panel is necessary for accurate assessment. Evidence is based on clinical practice and guidelines, not on direct studies from the provided context. Safety note: iron supplements for children should only be given under medical supervision and correct dosing.
