3. RBC Histogram Error Flag
When RBC histogram is not normal, a histogram error flag is added to the corresponding parameter
of the analysis value. Those histogram error flags are listed in the order of higher priority.
When 2 or more flags are applicable to a parameter, the highest-priority flag is used.
RL: Relative frequency for LOWER discriminator (LD) exceeds the range. Probable cause is the
effect of noise, RBC morphological change, platelet coagulation, or the like.
RU: Relative frequency for UPPER discriminator (UD) exceeds the range. Probable cause is the
effect of noise.
MP: 2 or more peaks in histogram.
DW: Particle distribution width error for 20% frequency with the peak taken as 100%. When the
20% frequency does not cross the histogram 2 times, this flag is attached.
• Matching of 8 kinds of RBC histogram error flags

: • When analysis results of LD and UD are normal.
• In the case of DW, when RDW-SD could be analyzed.
• In the case of MP, when RBC histogram has a single peak.
High: Frequencies of LD and UD are higher than the range.
×: • In the case of DW, when RDW-SD could not be analyzed.
• In the case of MP, when RBC histogram has 2 or more peaks.
: Any of “ ,” “×,” and “High” is applicable.
