You've reported that, " CBC result shows relative lymphocytosis and slight left shift percentage of lymphocytes 46% and bands 6%". A relative increase of lymphocytes indicates an increase in the participation of lymphocytes in among white blood cells (leucocytes), compared to the other 2 types of white blood cells: granulocytes and monocytes. Granulocytes usually make up 60% of all white blood cells, lymphocytes 30% and monocytes less than 10%. The relative values of each white cell component can vary, however from 20-45%. Higher amounts of lymphocytes among white blood cells are found in kids. A relative increase has no real medical meaning unless accompanied by an increase in the total number of lymphocytes, or the number of lymphocytes in 1 ml blood. Normal values are in the range of 1200-3200 lymphocytes in 1 ml blood.
