What is the most typical CBC finding in iron deficiency anemia in children?

Explanation:
Iron is essential for making hemoglobin, so when iron stores run low, red blood cells become smaller and paler due to reduced hemoglobin synthesis. This leads to a microcytic, hypochromic pattern on the CBC. Ferritin reflects stored iron, so it falls when stores are depleted, making low ferritin the hallmark of iron deficiency. In children, this classic combo—small, pale RBCs with low ferritin—best captures the typical CBC finding. Macrocytic or normocytic patterns are not the usual presentation for iron deficiency, and leukocytosis is not a characteristic feature.
