High white blood cells and red blood cells may be due to blood concentration because you did not drink water or eat on the morning of the blood draw. If you drink more water to increase blood circulation, it is possible that the white blood cells and red blood cells will return to normal. High white blood cells can also be seen after strenuous exercise or after a full meal, in a hot environment, or in a cold environment. High white blood cells can also be seen in some inflammatory diseases, such as rheumatoid arthritis, lobar pneumonia, purulent tonsillitis, and acute appendicitis, and are often accompanied by high neutrophils, which can be treated with antibiotics, such as cefixime tablets and levofloxacin hydrochloride capsules.
