Treatment is recommended when the patient’s white blood cells reach 21 x 10⁹/L, but fluids are not always needed. 1. Normal adult white blood cell count is (4~10)×10⁹/L. Increase is mostly seen in acute infections, especially bacterial infections. It can be treated with antibiotics such as levofloxacin under a doctor’s supervision. Antibiotics can be taken orally or infused intravenously, which should be decided in the light of the condition. 2. In addition to acute infections, severe trauma, extensive burns, intravascular hemolysis, acute hemorrhage, acute poisoning, leukemia and other diseases can also lead to increased white blood cells, according to the cause of the patient’s targeted treatment. For example, acute myeloid leukemia is treated with chemotherapy with drugs such as cytarabine. Intravenous administration is sometimes necessary for the treatment of patients. When the patient appears to have high white blood cells, should go to the hospital to find the cause of the disease, follow the doctor’s instructions to actively cooperate with the doctor’s treatment, do not self-medication, so as not to delay the condition or adverse reactions.
