Leukocytes at 22 x 109/L and neutrophils at 17 x 10⁹/L are abnormal and abnormal when above the normal range. It may be associated with severe infections and hematologic disorders. The normal range of peripheral blood leukocyte count in adults is (4-10) × 10⁹/L and the normal range of neutrophils (1.8-6.3 × 109/L) 1. In severe infections, activation of inflammatory factors, which in turn causes both leukocytes and neutrophils to rise. 2. Blood system diseases: such as leukemia, white blood cell and neutrophil indicators are high, with bone marrow abnormality leading to a large number of white blood cells and other massive reproduction, a large number of release into the peripheral blood, resulting in a rise in blood indicators, which may also be accompanied by a decrease in red blood cells and platelets. If the white blood cells and neutrophils are elevated, it is recommended to consult a doctor in time for a systematic examination to identify the cause of the disease and treat the symptoms.
