Appendix A: Parameter Denitions
Parameters presented in alphabetical order. All measured parameters except HGB are based on the
principle of impedance. HGB measurements are based on photometry. The expression of very low
values of some parameters has been limited due to low statistical signicance. The limits are given as
information.
HCT (Hematocrit)
The HCT is dened as being the packed volume of red cells in whole blood and is measured through
integration of total red blood cell count and the mean cell volume of the red blood cells. RBC counts
lower than around 0.20 do not generate an HCT.
HGB (Hemoglobin Concentration)
The hemoglobin is determined using a non-cyanide analytical method from a dilution of whole blood.
MCH (Mean Cell Hemoglobin)
The MCH is a calculated value and is dened as HGB/RBC giving the mean HGB concentration in
the red cells.
MCHC (Mean Cell Hemoglobin Concentration)
The MCHC is a calculated value and is dened as HGB/HCT.
MCV (Mean Cell Volume)
The MCV parameter is derived from the RBC size distribution curve of diluted blood. RBC counts
lower than around 0.20 do not generate an MCV value.
MPV (Mean Platelet Volume)
The mean cell volume of the platelets is determined from the PLT size distribution curve of diluted
blood. PLT counts lower than around 30 do not generate an MPV.
