WBC + differential
WBC (cells/ml) 4,500 - 10,000
Segmented neutrophils 54 - 62%

Monocytes 3 - 6 (3 - 7%)

Neutrophils (aka polymorphonuclear cells, PMNs, granulocytes, segmented neutrophils, or segs) fight against infection and represent a subset of the white blood count. Neutropenia by definition is an ANC below 1800/mm3 (some sources use a lower value).

Absolute neutrophil count (ANC) of 1000-1800: 
Most patients will be given chemotherapy in this range.
Risk of infection is considered low.

Mild neutropenia - Absolute neutrophil count (ANC) of 500-1000: 
Carries with it a moderate risk of infection.

Absolute neutrophil count (ANC) of less than 500:
Severe neutropenia - high risk of infection. Remember that a reduced WBC is known as leukopenia.

The WBC consists of the following (differential):
Lymphocytes: 20-40%
Neutrophils: 50-60%
Basophils: 0.5-2%
Eosinophils: 1-4%
Monocytes: 2-9% (average: 4%).
ANC = Total WBC x (% "Segs" + % "Bands")
Equivalent to: WBC x ((Segs/100) + (Bands/100))

The ANC refers to the total number of neutrophil granulocytes present in the blood.

Normal value: geq 1500 cells/mm3.
Mild neutropenia: geq1000 - <1500/mm3.
Moderate neutropenia: geq500 - <1000/mm3.
Severe neutropenia: < 500/mm3.
