The normal range of peripheral blood leukocyte count in adults is (4-10) × 109/L. When the leukocyte count is consistently higher than 10 × 109/L it is considered higher than normal and is called leukocytosis. There are many causes of elevated leukocytes, and we should take appropriate therapeutic measures according to the different causes.
Leukocytes is a general term for a category of cells in the blood, including neutrophils, eosinophils, basophils, lymphocytes, etc. On the one hand, if the increase in leukocytes is physiological after strenuous exercise or labor, during pregnancy and childbirth, or in severe cold or heat, there is no need for special treatment, and the number of leukocytes will return to normal when the body is free from these conditions.
On the other hand, if the neutrophilia is caused by acute infections caused by bacteria such as pneumonia and appendicitis, the patient should be treated with sensitive antibiotics; if the lymphocyte count increases during the acute phase of viral infections such as chickenpox, hepatitis and certain infectious diseases, the patient should be treated with antiviral drugs. In addition, if the eosinophils are elevated due to certain allergic diseases such as bronchial asthma, urticaria and parasitic infections, the patient should be treated with anti-allergy and anti-parasitic drugs.
When serious infectious diseases such as sepsis and septicemia occur, anti-infective treatment should be given to the pathogenic bacteria with drug sensitivity results. If the leukocyte count in the blood exceeds 200×109/L, the patient may develop leukocyte stasis, and dangerous symptoms such as respiratory distress, hypoxemia, unresponsiveness, slurred speech and intracranial hemorrhage may occur. arise, while actively treating the primary condition.
As mentioned above, there are many causes of leukocyte elevation, and we should take appropriate treatment measures according to the different causes. Therefore, when laboratory tests indicate that the leukocyte count is consistently higher than normal, prompt medical attention should be given to improve the systematic and formal examination and laboratory tests to make a clear diagnosis and then provide timely and accurate treatment.
