A 0.3 higher than normal blood white blood cell ratio may be caused by disease causes such as bacterial infections, or non-disease causes such as strenuous exercise. The normal range of blood white blood cells is (4-10)X10^9/L. When the white blood cell ratio is elevated, there may be various reasons, which need to be analyzed specifically. Usually people may have elevated leukocyte ratios when they are nervous, cold, hyperthermia, or just after strenuous exercise or eating, which is a physiologic elevation and requires no special treatment. In the event of bacterial infection, acute tissue injury, severe burns, large area scalded, etc., it is very easy to appear the phenomenon of elevated white blood cells, which belongs to the pathological elevation, and need to be treated under the guidance of the doctor to address the cause of the disease. In addition, in the case of poisoning, such as alcohol poisoning, or suffering from certain blood diseases, such as acute and chronic granulocytic leukemia, the above situation may also occur, and need to complete the relevant examinations in a timely manner, after a clear diagnosis and timely treatment.
