Neutrophils are the most abundant white blood cell type and the first responders to the site of infection or tissue injury. In a Differential Count, the percentage of neutrophils reflects the body's acute inflammatory response. They utilize phagocytosis and the release of antimicrobial enzymes to neutralize pathogens, particularly bacteria and fungi. An increase in the percentage (Neutrophilia) often signals an active bacterial infection.

Why Context Matters
Neutrophil counts can fluctuate due to acute physical or emotional stress, vigorous exercise, or the use of certain medications like corticosteroids, which 'demarginate' neutrophils from vessel walls, falsely raising the count without an infection.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
