Erythrocyte count

The number of red blood cells per unit volume in a sample of venous blood is called erythrocyte count.

RBC count

Separation and blood doping

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

The traditional method was to look at a blood smear and count the red blood cells.

Automated counters

There are many automated cell counters available that can do the task of counting the red blood cells easier and automatic.

Normal values

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.

CBC

Abnormal values

Low erythrocyte count is called anemia and increased erythrocyte count is called polycythemia
