Absolute neutrophils, lymphocytes or other cells from the WBC and differential.
Note
Absolute count = 8 × 60 % = 4.8 × 10³/µL (4,800 cells/µL).
Reference: Absolute count = total WBC × percentage / 100. For learning only. Reference intervals vary by laboratory, method and patient group; results are interpreted by qualified professionals with the clinical picture.
Absolute count = total WBC × differential % / 100
WBC 8.0 × 10³/µL, neutrophils 60 % → 4.8 × 10³/µL
A manual differential of 100 cells has a large sampling error; low counts are less precise.
