What is the standard white blood cell count range considered normal for adults?

• A. 3,500 to 7,000 cells per microliter
• B. 4,000 to 11,000 cells per microliter
• C. 8,000 to 12,000 cells per microliter
• D. 5,000 to 10,000 cells per microliter

Answer: (B)

The standard white blood cell count range considered normal for adults is 4,000 to 11,000 cells per microliter. This range is crucial because it reflects the number of white blood cells present in the bloodstream, which are vital for the immune system's functioning. A count within this range indicates that the body is maintaining a balanced immune response, which is essential for fighting infections and responding to diseases. Counts below or above this range could indicate various medical conditions. For instance, a lower count might suggest an increased risk of infections, while a higher count could point to an underlying infection, inflammation, or other medical issues. Understanding this reference range is important for healthcare professionals when interpreting laboratory results and diagnosing potential health concerns.
