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 and is called leukocytosis. There are many causes of elevated leukocytes, and the risk to the body is directly related to the primary condition causing the elevated leukocytes. The most common cases are as follows: when the body has various infectious diseases such as streptococcal pneumonia, parasitic infections, or necrotic diseases such as myocardial infarction, surgery, or 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 causing the white blood cell count to rise to varying degrees. In this case, the disease can be controlled after antibacterial and other related treatments are administered to address the cause of the disease.
However, when serious infectious diseases such as sepsis and septicemia occur, especially hematologic malignant diseases such as leukemia, the leukocyte count in the patient’s body may 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 and develop dangerous symptoms such as respiratory distress, hypoxemia, unresponsiveness, slurred speech and intracranial hemorrhage. the primary disease.
In summary, there are many causes of elevated leukocytes, which may be both an immune response of the body to clear harmful substances and a malignant disease response, and their degree of harm to the human body is also different. For increased leukocytes, standardized tests should be conducted to clarify the diagnosis and then make treatment.
