pancytopenia?

Answer Key with Rationale



Question 1: C) Low serum iron and low ferritin

• Rationale: In iron deficiency anemia, both serum iron and ferritin are low. Ferritin
reflects iron stores, and low ferritin is a hallmark of iron deficiency.



Question 2: C) Iron deficiency anemia

• Rationale: This patient's low serum iron, high TIBC, and low transferrin saturation are
characteristic of iron deficiency anemia, where the body increases TIBC to try to capture
more iron due to iron deficiency.

, Question 3: B) Low serum iron, high ferritin, low TIBC

• Rationale: In anemia of chronic illness, serum iron is low, ferritin is typically normal or
high due to inflammation, and TIBC is low or normal.



Question 4: B) High ferritin

• Rationale: High ferritin is commonly seen in iron overload disorders such as
hemochromatosis, as ferritin reflects the body’s stored iron, which accumulates in these
conditions.



Question 5: B) Aplastic anemia

• Rationale: Aplastic anemia is characterized by normal iron studies (serum iron, ferritin,
and TIBC). It results in pancytopenia due to bone marrow failure but does not affect iron
metabolism directly.



Question 6: B) Iron deficiency anemia

• Rationale: The patient's low serum iron, low ferritin, high TIBC, and low transferrin
saturation are consistent with iron deficiency anemia. The gastrointestinal bleeding likely
contributed to chronic iron loss.



Question 7: B) High serum iron, normal ferritin, normal TIBC

• Rationale: Hemolytic anemia often results in the release of iron from destroyed red
blood cells, leading to elevated serum iron, with normal or high ferritin levels and normal
TIBC.



Question 8: B) Normal serum iron, normal ferritin, normal TIBC

• Rationale: Pernicious anemia (Vitamin B12 deficiency) typically presents with normal
iron studies (serum iron, ferritin, and TIBC), as the anemia is due to vitamin B12
deficiency, not iron deficiency.
