Which value falls within the normal pediatric white blood cell count?

• A. 1,000-3,000
• B. 15,000-20,000
• C. 25,000-30,000
• D. 5,000-10,000

Answer: (D)

Understanding normal white blood cell counts in children helps distinguish healthy status from infection or inflammation. In healthy pediatric patients, the WBC count typically falls in a range around 5,000 to 10,000 cells per microliter. Values much lower, such as 1,000–3,000, signal leukopenia and potential bone marrow suppression or severe illness. Values well above normal, like 15,000–20,000 or 25,000–30,000, indicate leukocytosis often seen with infection, inflammation, or stress responses. Among the options, the 5,000–10,000 range best matches a normal pediatric WBC count.
