Calculate the absolute neutrophil count (ANC) for the following: WBC count of 5000 mm3; neutrophils (segs) of 10%; and nonsegmented neutrophils (bands) of 12%
a. 110/mm3
b. 500/mm3
c. 1100/mm3
d. 5000/mm3
ANS: C
Determine the total percentage of neutrophils ("polys," or "segs," and "bands"). Multiply white blood cell (WBC) count by percentage of neutrophils.
WBC = 1000/mm3, neutrophils = 7%, and nonsegmented neutrophils (bands) = 7%
Step 1: 10% + 12% = 22%
Step 2: 0.22 ? 5000 = 1100/mm3 ANC
