How many mL in 1 unit of packed red blood cells?

Answer 1

In 1mm3 of blood, there is 5 million red blood cells (erythrocytes), 10,000 white blood cells (leukocytes) and 300,000 platelets (rarely known as thrombocytes).

I answered a medical question and I'm only 15! Don't let that put you off. (Besides, I used a medical book to answer your question).

1mm3 is only a thousandth of a mL, therefore, 1mL of blood would have about a thousand times more of each. I.e. 5 billion RBCs, 10 million WBC, and about 250-300 million platelets

Answer 2

The red blood cell count is usually measured per micro liter of blood. Results may vary according to individuals though the normal range for males is between 4.7-6.1 million red blood cells per micro liter and for females the range is between 4.2-5.4 million cells per micro liter of blood.

The female red blood cell count is understood to be considerably lesser in comparison to their male counterparts because of the blood loss through menstruation every month. http://library.thinkquest.org/C0115080/?c=cbc
