Erythrocyte count
The number of red blood cells per unit volume in a sample of venous blood is called erythrocyte count.
Separation and blood doping[edit | edit source]
Red blood cells can be obtained from blood by a process known as centrifugation, that separates the cells from the blood plasma in a process known as blood fractionation.
Manual method[edit | edit source]
The traditional method was to look at a blood smear and count the red blood cells.
Automated counters[edit | edit source]
There are many automated cell counters available that can do the task of counting the red blood cells easier and automatic.
Normal values[edit | edit source]
The normal RBC range for men:4.7 to 6.1 million cells per microliter (mcL). The normal RBC range for women (non-pregnant) 4.2 to 5.4 million mcL.
Abnormal values[edit | edit source]
Low erythrocyte count is called anemia and increased erythrocyte count is called polycythemia
