2.3.3. HCT
The Hematocrit is a combination measurement of electronic pulses and mathematical calculations.
All the RBC pulses are grouped into various sizes. Each group pulse height is then averaged. all the
pulse height averages are then averaged one final time for a mean average of all the RBC pulse
heights. This is a function of the numeric integration of the MCV. Results are given as a percentage
of this integration.
2.3.4. MCV, MCH & MCHC
◆
MCV (Mean Cell Volume), is calculated directly from the entire RBC histogram.
◆
MCH (Mean Cell Hemoglobin), is calculated from the Hemoglobin value and the RBC count.
Calculations are as followed:
◆
MCHC (Mean Corpuscular Hemoglobin Concentration), is calculated according to the Hemo-
globin and Hematocrit values. Calculations are as followed:
2.3.5. RDW
The RDW (Red cell Distribution Width) is used to determine erythrocyte abnormalities linked to
Anisocytosis. The RDW will enable you to follow the evolution of the width of the RBC Histogram in
relation to the number of cells and their average volume. This is also a calculation of the RBC His-
togram.
Calculations are as followed:
K : ..........Calibration Coefficient for RDW.
SD : .........Standard Deviation according to statistical studies on cell distribution.
MCV : .......(Mean Cell Volume) of the erythrocytes.
2.3.6. MPV
The MPV (Mean Platelet Volume), is directly calculated from the Platelet histogram distribution
curve. This calculation is almost the same as the MCV.
2.3.7. PCT
Thrombocrit (Plateletcrit), is calculated according to the formula:

MCH (pg) =HGB/RBC x 10
(pg): Picograms
MCHC (g/dl) = HGB/HCT X 100
RDW (%) = K SD/MCV
