Dr. Zhou Xiaofeng
A white blood cell count of 40,000/μL in children is a relatively high value, usually indicating a possible severe infection or hematologic disorder.
1. Possibility of infection: An elevated white blood cell count is often associated with infections, especially when the white cell count increases, which may be caused by bacteria, viruses, or other pathogens. In such cases, prompt medical attention is required for anti-inflammatory intravenous therapy, and the child's fever should be monitored; oral antipyretics are recommended if the temperature exceeds 38.5°C.
2. Hematologic disorders: In addition to infection, a high white blood cell count may also be related to hematologic diseases, such as leukemia. Therefore, when an abnormally high white blood cell count is detected in a child, the possibility of these diseases should be taken seriously, and further diagnostic tests and treatment should be promptly pursued.
