What is the typical range for pediatric white blood cell counts?

  1. 1,000-5,000

  2. 5,000-10,000

  3. 10,000-15,000

  4. 15,000-20,000

The correct answer is: 5,000-10,000

The typical range for pediatric white blood cell counts generally falls between 5,000 and 10,000 cells per microliter of blood. This range is significant because white blood cells play a crucial role in the immune system, helping to protect the body from infections and other diseases. In pediatric populations, white blood cell counts can vary with age and can be influenced by factors such as activity level, stress, and any underlying health conditions. While adults typically have a WBC count around 4,000 to 11,000 cells per microliter, children can have slightly higher normal ranges, particularly in younger ages. The other ranges presented either suggest counts that are too low or excessively high for pediatric patients, which would not be typically expected in healthy children. Therefore, recognizing the standard range of 5,000-10,000 helps in assessing a child's immune status and identifying potential health issues.
