An MCV value below the normal reference range suggests

An MCV value below the normal reference range suggests

• A. Hyperchromasia
• B. Hypochromasia
• C. Macrocytosis
• D. Microcytosis

Answer: (D)

Mean corpuscular volume reflects the average size of red blood cells. When MCV is below the normal range, the red cells are smaller than usual, a finding called microcytosis. This pattern is commonly seen with iron deficiency anemia or chronic blood loss and often accompanies reduced hemoglobin content in cells. In contrast, a high MCV would indicate macrocytosis (larger cells). Hypochromasia refers to decreased color (hemoglobin) per cell and is a separate attribute, while hyperchromasia would mean abnormally dense hemoglobin, not small cell size.
