The expected number of RBCs in a single drop, or microliter, of blood is 4.5 to 6.2 million in men and 4.0 to 5.2 million in women.

A. 2,500 and 09,300
B. 4,500 and 10,000
C. 4,900 and 12,000
D. None of these

The normal range is 4,500 to 10,000 cells per microliter (cells/mcL). (A microliter is a very tiny amount – one millionth of a liter).
