The increase in number of erythrocytes is called erythropenia
Normally the reticuloycytes are 0.5 - 1% of erythrocytes number
The increase in number of the leucocytes is called leucocytosis
The number of the leucocytes is from 4.10^9/I to 10.10^10/I
The number of blood platelets (thrombocytes) is 20.10^9/I - 40.10^9/I
The basophils (basophil granulocytes) are about 4-8% of the total number of leucocytes
