The cells on the left appear smaller than the normal cells on the right. The mean cell volumes, however, are about equal. The small, more darkly stained red cells without central pallor are spherocytes. Note that they appear hyperchromic and contain a greater amount of hemoglobin that normal. Normal blood may contain a few spherocytes, but the blood on the left is from a patient with hereditary spherocytosis.
