1. The normal range of lymphocyte percentage is between 20% and 40%. If the lymphocyte percentage is 18.6%, the white blood cell count is normal and there is no clinical symptom, it may be a physiological phenomenon and does not need special treatment.
2. If the lymphocyte percentage is 18.6%, accompanied by increased neutrophil count, increased white blood cell count, and normal absolute lymphocyte value, then it is considered that there is a bacterial infection, which leads to increased neutrophil count and relatively low lymphocyte ratio, and there are inflammatory manifestations such as fever, coughing and coughing up sputum, and it is necessary to go to the hospital to carry out anti-infective (levofloxacin) and other related treatments.
In addition, pathologic factors include acute myeloid leukemia and chronic granulocytic leukemia, which need to be diagnosed under the guidance of a physician.
