Eosinophil calculations - 1
Formulas for Eos calculations in #eos/mm3:
Eos
= (#Eos/2 chambers)(DCF)(VCF)
Example:
Following
counts obtained in both chambers:
Side
#1 = 12
Total = 27
Side
#2 = 15
Eos
= (#Eos/2 chambers)(DCF)(VCF)
DCF
= 32
VCF
= 0.55
Eos
= (27)(32)(0.55)
Eos
= 480/mm3
Eosinophils =0.48 x 109/L
