The megaloblastic anemia, the average volume of red blood cells increases, the average hemoglobin content of red blood cells increases, the average hemoglobin concentration of red blood cells is normal, and the distribution width of red blood cells increases.

5. Average platelet volume: The average volume of each platelet, the size of which is related to its function.
