Given a WBC of 2.1 with neutrophils 22% and bands 4%, what is the ANC?

Explanation:
ANC is found by multiplying the total WBC by the fraction of neutrophils, including bands since they are immature neutrophils. Add the neutrophil and band percentages: 22% + 4% = 26%, which is 0.26 as a decimal. Multiply by the WBC: 2.1 × 0.26 = 0.546 (in units of 10^9/L). Expressed as cells per microliter, 0.546 × 10^9/L equals 546 cells/µL. So the ANC is 546.
