Neutrophils (Absolute)
The absolute neutrophil count (ANC) is the actual number of neutrophils in a volume of your blood, calculated from your total white cell count and the neutrophil percentage. Neutrophils are your front-line defenders against bacteria.
The absolute count is more clinically meaningful than the percentage because it reflects the real number of infection-fighting cells you have on hand. Clinicians rely on it to judge your risk of infection, particularly during treatments that suppress the marrow.
An above-range ANC (neutrophilia) commonly reflects bacterial infection, inflammation, tissue injury, physical or emotional stress, or steroid use. Marked or persistent elevations may prompt a look for less common marrow causes.
A below-range ANC (neutropenia) reduces your ability to fight bacterial infection and can result from viral illness, certain medications, chemotherapy, or marrow conditions; very low counts need prompt medical attention.
A typical adult ANC runs roughly 1,500-8,000 cells per microliter, though targets shift during certain treatments. Interpret any value with your clinician in the context of your health.
