See this page from Washington University to see sample values. They also show a method to calculate it which is accurate but I find is not intuitive. See page here: HowtoCalculateANC
The following intuitive formula gives an easy way to calculate the ANC.
To find out your ANC, multiply the percentage of neutrophils by the total number of WBCs ( in thousands). Neutrophils are sometimes called segs or polys, and young neutrophils may be called bands on your lab report. If bands are listed as a percentage of WBCs, add them to the neutrophils before multiplying.
You can figure out your ANC using this formula:
ANC= (Total WBC) x [(% of neutrophils + % of bands) ÷ 100]
Because you are multiplying, the denominator of the second item (% of Neut + % bands) also applies to the first item (total WBC count). That means this formula can also be written as:
ANC = (total WBC x % [PMNs + bands]) ÷ 100
Note that the total WBC needs to be expressed in thousands. For example, a WBC of 2 x 103 becomes 2,000.
For example, if the WBC count is 2,000, with 65% neutrophils and 5% bands, then the ANC is 1,400, which is calculated like this:
ANC = [(65 + 5) ÷ 100] × 2,000
ANC = (70 ÷ 100) × 2,000
ANC = 0.7 × 2,000 = 1,400
In the washington university example above, the lab values are: WBC 2 or 2000; Polys=14.8%; and Bands = 5%
ANC = 2000 x [(14.8 + 5) /100] = 396
**Most patients on chemotherapy will experience a nadir in her absolute neutrophil count (ANC) five to ten days after completion of a chemotherapy session.
