How do you calculate ANC?

WBC x [( % segs + % bands )/100]
WBC + [( % segs + % bands )/100]
WBC / [( % segs + % bands )/100]
WBC - [( % segs + % bands )/100]

The correct answer is: WBC x [( % segs + % bands )/100]

ANC, or Absolute Neutrophil Count, is calculated by multiplying the Total White Blood Cell (WBC) count by the sum of the percentage of segmented neutrophils and the percentage of band neutrophils divided by 100. This equation is represented by WBC x [( % segs + % bands )/100]. This is because the ANC is a measure of the total number of neutrophils in the blood, which is determined by adding together both the segmented neutrophils and the band neutrophils. The other options (B, C, D) are incorrect because they have incorrect mathematical operations - addition, division, and subtraction respectively - which do not accurately represent the ANC calculation.
