What is the normal range for white blood cells (WBCs)?

The normal range for white blood cells (WBCs) is typically considered to be 5,000 to 10,000 cells per microliter (cells/mcL) of blood. This range reflects the quantity of WBCs, which play a vital role in the immune system by helping to fight infections and protect the body from various diseases.

Within this range, individual factors like age, sex, and overall health can lead to variations. However, values outside this range might suggest underlying health conditions, such as infections, immune system disorders, or blood-related diseases. Monitoring WBC counts is an important aspect of assessing a patient's health status during clinical evaluations.

The other ranges provided do not align with established clinical standards for normal WBC counts, which is why they are not considered correct. Understanding the normal range for WBCs is critical for recognizing abnormal findings in laboratory results and making informed clinical decisions.
