A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should. A normal ANC is over 1,000. By using the value of WBC count: If doctors prescribed both WBC count as well as Absolute Neutrophil Count, then the formula is: multiply your white blood count (WBC) x total neutrophils (segmented neutrophils% + segmented bands%) x 10 = ANC.For example: WBC = 2.0, segmented Neutrophils = 14.8% and Bands 5%, then according to this formula, ANC= [{2 X (14.8+5)} X 10] = 396.Image 2: ANC (absolute neutrophil count) 1. Then a correction is made as follow s: Corrected WBC = obtained nucleated cell count x [100 ÷ (nRBC + 100)] Example: If your WBC is 2.0, segs are 14.8% and bands are 5.0% the formula would look like this: 2.0 x (14.8 + 5.0) = 2.0 x 19.8 = 39.6 / 100 = .396 The ANC is 0.396 To complete the diagnosis, you need to provide the neutrophils count, bands count and white blood cell count. WBC * ( (segs / 100) + (bands / 100)) (2) Segs and bands reported in total numbers: ANC = (segs + bands) x 1000. Instructions. Note down the number of white blood cells (WBC) per microliter.
