A normal red blood cell count ranges between 4.5 and 5.3 million cells/μL for males ages 12 to 18 years, while the range is 4.1 to 5.1 million cells/μL for females of the same age group.

“Mature red blood cells don’t have organelles, such as mitochondria,” said co-corresponding author Jian Xu, PhD, St. Jude Department of Pathology and Center of Excellence for Leukemia Studies.

The morphology of the red blood cells in the peripheral blood smears was quite bizarre, with marked anisocytosis and poikilocytosis, numerous so-called "helmet cells" and small fragmented portions ...
