Question
Today’s blood routine test shows that the white blood cell count (WBC) in a child is approximately 16,000, but no symptoms have appeared. Is this count normal?
Answer
Whether a child’s white blood cell count is normal depends on their age. For newborns, this value falls within the normal range. The normal white blood cell count in adult peripheral blood typically ranges between 4～10×10^9/L; counts below 4×10^9/L are considered low, and counts above 10×10^9/L are considered elevated, which may be related to infection. It is recommended to visit a regular medical institution for detailed examination and treatment.
