What laboratory test result indicates iron deficiency anemia?

• A. Serum Ferritin below 12ng/Litre
• B. Hemoglobin above 160g/L
• C. White blood cell count above normal
• D. Platelet count below 100,000/uL

Answer: (A)

The presence of a serum ferritin level below 12 ng/L is a strong indicator of iron deficiency anemia. Ferritin is a protein that stores iron in the body, and its levels reflect the amount of stored iron available. When ferritin levels drop significantly, it suggests that the body’s iron stores are depleted, which can lead to a decrease in hemoglobin production and result in iron deficiency anemia. In contrast, a hemoglobin level above 160 g/L suggests that the individual may not be experiencing anemia, as this value typically indicates adequate hemoglobin levels. An elevated white blood cell count generally points to an infection or inflammation rather than anemia. Additionally, a platelet count below 100,000/uL indicates thrombocytopenia, which is not a direct indicator of iron deficiency anemia. Therefore, the serum ferritin level being below 12 ng/L is the most relevant laboratory test result in diagnosing iron deficiency anemia.
