Retic Ch Histogram - Siemens ADVIA 2120 Operator's Manual

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.

cellular hemoglobin greater than 31 pg
Percentage of gated cell population with cellular
hemoglobin greater than 31 pg
Percentage of reticulocyte population with
cellular hemoglobin less than 27 pg
Percentage of mature RBC population with
cellular hemoglobin less than 27 pg
Percentage of gated cell population with cellular
hemoglobin less than 27 pg
Cellular Hemoglobin Mean is the mean of the
RETIC CH histogram for the reticulocyte
population.
Cellular Hemoglobin Mean is the mean of the
RETIC CH histogram for the mature RBC
population.
Cellular Hemoglobin Mean is the mean of the
RETIC CH histogram for the gated cells.

Cellular Hemoglobin Distribution Width is the
standard deviation (SD) of the RETIC CH
histogram for the reticulocyte population.
Cellular Hemoglobin Distribution Width is the
