A patient is presented with pallor, fatigue and dyspnea. Physical examination shows koilonychias and angular cheilosis. Which of the following is not expected in the laboratory finding of this patient?

Correct Answer: B

Rationale: Pallor, fatigue, dyspnea, koilonychias (spoon nails), and angular cheilosis suggest iron deficiency anemia. Expected lab findings include low serum ferritin (D), low iron:TIBC ratio (C), and high total iron binding capacity (TIBC) due to increased transferrin production. Low TIBC (A) is not typical; TIBC is usually elevated in iron deficiency. High serum transferrin (B) is expected, as transferrin increases to bind scarce iron, making B the *not expected* finding if misinterpreted as abnormal—however, it’s typically high, so A is the outlier.
