What should be done if a routine blood test shows an elevated white blood cell count?

In the case of elevated white blood cell count detected by routine blood examination, one should first maintain a calm mindset and avoid anxiety or stress, which may worsen the condition. Next, it is important to identify the underlying cause. Increased white blood cell counts are commonly seen in infections (such as bacterial or viral infections), allergic reactions, severe tissue injury or necrosis, and acute poisoning. According to the specific cause, appropriate treatment measures should be taken: For infectious diseases, anti-infective treatment is required, using antibiotics or antiviral medications. In cases of allergies, antihistamines may be used. Hematologic or immune system disorders may require treatment with immunosuppressants, glucocorticoids, or other medications depending on the specific condition. At the same time, attention should be given to lifestyle adjustments, including adequate rest, a light diet, avoiding spicy or greasy foods, and increased intake of fresh vegetables and fruits to enhance the body's resistance. If symptoms persist or worsen, timely medical consultation is necessary, and further investigations and treatments should be conducted under a physician's guidance.
