measures and calculates 20 parameters, listed below. For each parameter
we list the name, abbreviation and measurement unit in the first column. Short
description for each parameter is in the second column.
White Blood Cells – WBC
(cells/l, cells/µl)
Number of leukocytes
WBC = WBC
cal
x counted WBC (cells/l, cells/µl)
Red Blood Cells – RBC
(cells/l, cells/µl)
Number of erythrocytes
RBC = RBC
cal
x counted RBC (cells/l, cells/µl)
Hemoglobin concentration - HGB
(g/dl, g/l, mmol/l)
Measured photometrically at 540 nm; in each cycle blank
measurement is performed on diluent
HGB = HGB
cal
x (HGB
measured
– HGB
blank
)
Mean Corpuscular Volume - MCV
(fl)
Average volume of individual erythrocytes derived from
the RBC histogram.
Hematocrit – HCT
(percentage, absolute)
Calculated from the RBC and MCV values.
HCT
percentage
= RBC x MCV x 100
HCT
absolute
= RBC x MCV
Mean Corpuscular Hemoglobin – MCH
(pg, fmol)
Average hemoglobin content of erythrocytes, calculated
from RBC and HGB values.
MCH = HGB / RBC
Mean Corpuscular Hemoglobin
Concentration – MCHC
(g/dl, g/l, mmol/l)
Calculated from the HGB and HCT values.
MCHC = HGB / HCT
absolute
Unit of measurement is displayed according to the one
chosen for HGB result (g/dl, g/l or mmol/l)
Red Cell Distribution Width – RDW-SD
(fl)
Platelet Distribution Width – PDW-SD
(fl)
Red cell Distribution Width – RDW-CV
(absolute)
Platelet Distribution Width – PDW-CV
(absolute)
The distribution width of the erythrocyte or platelet
population derived from the histogram at 20% of peak
xDW-SD = RDW
cal
x (P2 - P1) (fl),
xDW-CV = RDW
cal
x 0.56 x (P2 - P1) / (P2 + P1)
by the factor of 0.56 CV is corrected to the 60% cut
Platelet – PLT
(cells/l, cells/µl)
Number of thrombocytes (platelets)
PLT = PLT
cal
x counted PLT (cells/l, cells/µl)
Mean Platelet Volume – MPV
(fl)
Average volume of individual platelets derived from the
PLT histogram
Thrombocrit – PCT
(percentage, absolute)
Calculated from the PLT and MPV values
PCT
percentage
= PLT x MPV x 100
PCT
absolute
= PLT x MPV
White blood cell 3-part differential:
LYM, LYM% : lymphocytes
MON, MON% : monocytes and some
eosinophils
GRA, GRA%: granulocytes
Absolute values counted in the channels determined by
the three WBC discriminators:
