Question
A 10-year-old boy has a persistently elevated white blood cell count, and his parents are concerned and hope to receive professional medical advice.
Answer
Firstly, it is necessary to determine the specific cause of the elevated white blood cell count to enable targeted treatment. Possible causes include bacterial infections. It is recommended to actively use antibiotic treatment and undergo chest X-rays and routine blood tests to assess the presence of pulmonary infections. From the laboratory results, it appears that there may be inflammation in the respiratory tract of the boy, and the type of white blood cells indicates signs of bacterial infection. The boy should undergo a chest X-ray and routine blood re-examination. If the boy has phlegm, sputum culture and drug sensitivity tests can be performed, which will help guide clinical medication.
