The normal range of peripheral blood leukocyte count in adults is (4-10) x 109/L. When the leukocyte count is consistently higher than 10 x 109/L it is considered higher than normal, therefore a leukocyte count of 22.5 x 109/L is considered leukocytosis and is an abnormal condition. When the human body has various infectious diseases such as streptococcal pneumonia, parasitic infections, or necrotic diseases such as myocardial infarction, surgery, and immune system diseases such as rheumatoid diseases, the immune system in the patient’s body will play a protective role to remove harmful substances from the body, thus The immune system in the patient’s body will play a protective role to remove the harmful substances from the body, thus causing the leukocyte count to rise to different degrees. In this case, the disease can be controlled by antibacterial and other related treatments.
However, when serious infectious diseases such as sepsis and septicemia occur, especially hematologic malignant diseases such as leukemia, the white blood cell count can increase significantly, up to tens of times the normal level. If the leukocyte count in the blood exceeds 200×109/L, the patient may develop leukocyte stasis, with dangerous symptoms such as respiratory distress, hypoxemia, unresponsiveness, slurred speech and intracranial hemorrhage. At this time, when the leukocyte count in the blood exceeds 100×109/L, emergency treatment measures such as drug control or blood cell separator should be taken to prevent complications.
Therefore, a leukocyte count of 22.5×109/L is considered leukocytosis, and its degree of danger is directly related to the primary disease that caused the leukocytosis, so timely consultation should be made to improve systematic and formal examination and laboratory tests, and timely and accurate treatment should be carried out after a clear diagnosis.
