Methods
RBC Rate Histogram
The RBC Rate histogram
shows the uniformity of the
cell-counting rate.
.
The rate histogram data consists of 50 points, one taken every 200 milliseconds.
Each point represents the number of valid cells counted during the last 200
milliseconds
RBC Volume Histogram
The RBC Volume histogram represents the distribution of red blood cells by cell
volume. The histogram has a range of 0 fL to 200 fL.
RBC Volume histogram (normal sample)
1
Microcytic region
2
Normocytic region
3
Macrocytic region
4
60 fL marker
5
120 fL marker
Normal samples have a bell-curve shaped distribution with a mode channel
between 60 fL and 120 fL. The mean corpuscular volume (MCV) and the red cell
distribution width (RDW) are determined from this histogram. The MCV is the
mean of the of RBC Volume histogram. The RDW is the coefficient of variation
of the population. The MCV calibration factor has been applied to the displayed
data.
