Methods
CHDWg
Cellular Hemoglobin Distribution Width is the
standard deviation (SD) of the RETIC CH
histogram for the gated cells.
CHDW Delta
CHDWr - CHDWm
RETIC Scatter Abs Cytogram
The RETIC Scatter ABS cytogram is the graphical representation of the
absorption and light-scatter measurements: the high-gain, absorption (cell
maturation) is plotted along the x axis and the high-angle, low-gain light scatter
(cell size) is plotted along the y axis.
1 RTC Platelet threshold
2 RTC Coincidence threshold
3 RTC threshold
4 Low/Medium RTC threshold
5 Medium/High RTC threshold
A Mature RBCs
B Low absorption retics
C Medium absorption retics
D High absorption retics
E Platelets
F Coincidence events
The two thresholds on the y axis (1)(2) are set as follows:
1.
The analyzer scans for the scatter mode between channels 10 and 99 on the y
axis.
2.
The mean channel and standard deviation (SD) are calculated.
3.
The RTC Platelet threshold (1) is set at the mean channel minus 3.5 SD to
separate the platelets from the mature RBCs and reticulocytes.
4.
The RTC Coincidence threshold (2) is set at the mean channel plus 3.5 SD to
separate the coincident cells from the mature RBCs and reticulocytes.
The RTC threshold (3) on the x axis is set as follows:
