The cause of elevated white blood cells is emotional, painful irritation, neonatal period, usually without other abnormalities and discomfort, which does not require special treatment and can return to normal.
Superior respiratory infections are a common cause of leukocytosis and are often associated with fever, cough, and sputum, which can be cured with anti-infection, symptomatic treatment, and supportive therapy.
Urinary tract infections are also common with elevated leukocytes. Patients may have uncomfortable symptoms such as frequent, urgent, and painful urination, and elevated urine and blood leukocytes, which resolve with anti-infective and symptomatic treatment and return to normal indicators.
Bone marrow hematopoietic abnormalities are also a common cause of leukocyte hyperplasia. In addition to increased leukocytes, abnormalities in red blood cells, platelets and hemoglobin are also seen. Bone marrow aspiration biopsy can provide a clear diagnosis and early treatment is more effective, but it is easy to relapse, so increased leukocytes must be taken seriously and the cause further clarified to avoid delaying the disease due to improper treatment and missing the best time for treatment.
