What are the critical value range and normal value for white blood cells?

Generally, the critical value of white blood cells (WBC) is below 2*10^9/L and above 11*10^9/L, with a normal range of 4*10^9/L to 10*10^9/L. The normality of WBC depends on its level change. WBC is a crucial component of the human immune system, and its changes can indicate acute infection, acute hemorrhage, leukemia, aplastic anemia, and other diseases. Under normal conditions, the WBC count ranges from 4*10^9/L to 10*10^9/L, and if it falls within this range, it is generally considered normal and there is no need for excessive concern. However, if the WBC count is below 2*10^9/L or above 11*10^9/L, it indicates that the body's immune system has been affected, and further examination is needed to determine the underlying cause. Targeted treatment measures should be taken based on the cause to prevent the condition from progressing. In daily life, it is essential to pay attention to bodily changes and consume fiber-rich foods such as celery and spinach to supplement necessary vitamins and accelerate metabolism. If any other discomfort occurs, prompt and standardized treatment should be sought.
