Formulas to Calculate Absolute Values from Percentage Values of White Blood Cell count for Neutrophil, Lymphocyte Etc.,

The formula to calculate the Absolute Neutrophil Count (ANC) 
from the neutrophils percentage is:

ANC=WBC×(Neutrophils (%)/100)\text{ANC} = \text{WBC} \times (\text{Neutrophils (\%)} / 100)

Where:

  • ANC = Absolute Neutrophil Count (typically measured in cells/µL).
  • WBC = Total White Blood Cell count (usually measured in cells/µL).
  • Neutrophils (%) = Percentage of neutrophils in the total white blood cell count.

Example:

If:

  • WBC = 10,000 cells/µL
  • Neutrophils (%) = 70%
ANC=10,000×(70/100)=7,000 cells/µL\text{ANC} = 10,000 \times (70 / 100) = 7,000 \, \text{cells/µL}

The formula to calculate the Absolute Lymphocyte Count (ALC) 
from the lymphocyte percentage is:

ALC=WBC×(Lymphocytes (%)100)\text{ALC} = \text{WBC} \times \left(\frac{\text{Lymphocytes (\%)}}{100}\right)

Where:

  • ALC = Absolute Lymphocyte Count (typically measured in cells/µL).
  • WBC = Total White Blood Cell count (measured in cells/µL).
  • Lymphocytes (%) = Percentage of lymphocytes in the total white blood cell count.

Example:

If:

  • WBC = 8,000 cells/µL
  • Lymphocytes (%) = 30%
ALC=8,000×(30100)=2,400 cells/µL\text{ALC} = 8,000 \times \left(\frac{30}{100}\right) = 2,400 \, \text{cells/µL}


The formula to calculate the Absolute Eosinophil Count (AEC)
from the eosinophil percentage is:

AEC=WBC×(Eosinophils (%)100)\text{AEC} = \text{WBC} \times \left(\frac{\text{Eosinophils (\%)}}{100}\right)

Where:

  • AEC = Absolute Eosinophil Count (typically measured in cells/µL).
  • WBC = Total White Blood Cell count (measured in cells/µL).
  • Eosinophils (%) = Percentage of eosinophils in the total white blood cell count.

Example:

If:

  • WBC = 6,000 cells/µL
  • Eosinophils (%) = 5%
AEC=6,000×(5100)=300 cells/µL\text{AEC} = 6,000 \times \left(\frac{5}{100}\right) = 300 \, \text{cells/µL}

The formula to calculate the Absolute Monocyte Count (AMC) 
from the monocyte percentage is:

AMC=WBC×(Monocytes (%)100)\text{AMC} = \text{WBC} \times \left(\frac{\text{Monocytes (\%)}}{100}\right)

Where:

  • AMC = Absolute Monocyte Count (typically measured in cells/µL).
  • WBC = Total White Blood Cell count (measured in cells/µL).
  • Monocytes (%) = Percentage of monocytes in the total white blood cell count.

Example:

If:

  • WBC = 7,500 cells/µL
  • Monocytes (%) = 8%
AMC=7,500×(8100)=600 cells/µL\text{AMC} = 7,500 \times \left(\frac{8}{100}\right) = 600 \, \text{cells/µL}
The formula to calculate the Absolute Basophil Count (ABC) 
from the basophil percentage is:

ABC=WBC×(Basophils (%)100)\text{ABC} = \text{WBC} \times \left(\frac{\text{Basophils (\%)}}{100}\right)

Where:

  • ABC = Absolute Basophil Count (typically measured in cells/µL).
  • WBC = Total White Blood Cell count (measured in cells/µL).
  • Basophils (%) = Percentage of basophils in the total white blood cell count.

Example:

If:

  • WBC = 5,000 cells/µL
  • Basophils (%) = 2%
ABC=5,000×(2100)=100 cells/µL\text{ABC} = 5,000 \times \left(\frac{2}{100}\right) = 100 \, \text{cells/µL}
