What is a normal white blood cell count for a healthy adult?

• A. 3000 - 5000
• B. 3500 - 10500
• C. 4000 - 15000
• D. 2000 - 10000

Answer: (B)

A normal white blood cell (WBC) count for a healthy adult typically ranges from about 4,000 to 11,000 white blood cells per microliter of blood. This range is important because it reflects the body’s ability to respond to infections, inflammation, and other immune challenges. The range provided in the correct choice encompasses the commonly accepted reference values, indicating that it allows for slight variations while still being within the realms of normalcy due to factors such as the individual’s age, health status, and even time of day. WBC counts outside this normal range may suggest a variety of health issues, such as infections, bone marrow problems, or immune system disorders, making it crucial for medical professionals to understand these values for diagnosis and treatment. Understanding the normal ranges helps in recognizing abnormalities that may require further investigation or intervention.
