What is the normal range for neutrophils in the blood?

The normal range for neutrophils in the blood is typically between 55% and 70% of the total white blood cell count. Neutrophils are a type of white blood cell that plays a crucial role in the immune response, particularly in fighting off bacterial infections.

The percentage of neutrophils can vary based on several factors including age, sex, and health status, but this range is generally accepted in clinical practice as standard. A neutrophil percentage outside this range may indicate an underlying health issue; for instance, lower levels can suggest conditions such as bone marrow disorders or severe infections, while higher levels may indicate active infection or inflammation.

Understanding the normal range of neutrophils is important for diagnosing and monitoring various medical conditions, and it provides a baseline for evaluating a patient's immune function.
