Absolute neutrophil count (ANC) is the number of neutrophils (a type of white cell) a person has in his or her blood that will fight an infection.

ANC is measured in cells per cubic millimeter (cells/mm3).

Normal value for ANC is greater than or equal to 1500 cells/mm3.

What the results mean

Mild Neutropenia: 1000-1500 cells / mm3. Low risk of infection.
Moderate Neutropenia: 500-999 cells / mm3. Increased risk of infection.
Severe Neutropenia: < 500 cells / mm3. High risk for severe infection.
