What does neutrophilia indicate in a patient?

Neutrophilia indicates an increased number of neutrophils in the bloodstream. Neutrophils are a type of white blood cell that play a critical role in the immune response, primarily in fighting off infections and responding to injury. When neutrophilia is observed, it typically suggests the presence of an underlying condition, such as an infection, inflammation, stress response, or may occur as a reaction to certain medications.

The increase in neutrophil count often reflects the body's response to a triggering factor, such as bacterial infections or tissue injury, where the body requires more neutrophils to combat perceived threats. Monitoring neutrophil levels can be significant in diagnosing and managing various medical conditions.
