There isn't an exact 'normal' figure for the number of cells in your blood (called your blood count). 'Normal' for a large man wouldn't be the same as for a small woman. But generally the normal white cell count is between about 4,000 and 11,000 cells per cubic millimetre of blood.here isn't an exact 'normal' figure for the number of cells in your blood (called your blood count).

Different laboratories classify low white blood cell counts differently. Generally, a count lower than 3,500 white blood cells per microliter of blood is considered a low white blood cell count. But ask your doctor what the normal range is for the laboratory he or she uses.It may also be helpful to discuss exactly how far outside that range your number falls.enerally, a count lower than 3,500 white blood cells per microliter of blood is considered a low white blood cell count.
