Methods
Explanation
CSF WBC/μL = (CSF PHA WBC / CSF
PHA Total x CSF PHA Cells) / (1-
Fractional Dead Time) x Perox Nominal
Factor
%CSF PMN = 100 x CSF PMN / CSF
WBC
#CSF PMN/μL = (CSF PHA PMN / CSF
PHA Total x CSF PHA Cells) / (1-
Fractional Dead Time) x Perox Nominal
Factor
%CSF MN = 100 x CSF MN / CSF WBC
#CSF MN/μL = (CSF PHA MN / CSF PHA
Total x CSF PHA Cells) / (1-Fractional
Dead Time) x Perox Nominal Factor
%CSF Neut = 100 x CSF Neut / CSF WBC
#CSF Neut/μL = (CSF PHA Neut / CSF
PHA Total x CSF PHA Cells) / (1-
Fractional Dead Time) x Perox Nominal
Factor
%CSF Lymph = 100 x CSF Lymph / CSF
WBC
#CSF Lymph /μL = (CSF PHA Lymph /
CSF PHA Total x CSF PHA Cells) / (1-
Fractional Dead Time) x Perox Nominal
Factor
%CSF Mono = 100 x CSF Mono / CSF
WBC
#CSF Mono/μL = (CSF PHA Mono / CSF
PHA Total x CSF PHA Cells) / (1-
Fractional Dead Time) x Perox Nominal
Factor
CSF RBC/μL = (CSF R Count / CSF PHA
Total x CSF PHA Cells) / (1-Fractional
Dead Time) x Perox Nominal Factor
