RETIC CH Histogram
The RETIC cellular hemoglobin (RETIC CH) histogram represents the overlaid
distributions of mature RBCs and reticulocytes by the actual weight or mass of
hemoglobin present in each cell. The histogram has a range from 0 pg to 100 pg.
Mature RBC population

Reticulocyte population

RETIC CH Histogram Parameters
%HIGH CHr
Percentage of reticulocyte population with
cellular hemoglobin greater than 31 pg
%HIGH CHm Percentage of mature RBC population with
cellular hemoglobin greater than 31 pg
%HIGH CHg
Percentage of gated cell population with cellular
hemoglobin greater than 31 pg
%LOW CHr
Percentage of reticulocyte population with
cellular hemoglobin less than 27 pg
%LOW CHm
Percentage of mature RBC population with
cellular hemoglobin less than 27 pg
%LOW CHg
Percentage of gated cell population with cellular
hemoglobin less than 27 pg
CHr
Cellular Hemoglobin Mean is the mean of the
RETIC CH histogram for the reticulocyte
population.
CHm
Cellular Hemoglobin Mean is the mean of the
RETIC CH histogram for the mature RBC
population.
CHg
Cellular Hemoglobin Mean is the mean of the
RETIC CH histogram for the gated cells.
CH Delta
CHr - CHm
CHDWr
Cellular Hemoglobin Distribution Width is the
standard deviation (SD) of the RETIC CH
histogram for the reticulocyte population.
CHDWm
Cellular Hemoglobin Distribution Width is the
standard deviation (SD) of the RETIC CH
histogram for the mature RBC population.
