5) 2B High UD with 20%-frequency distribution width error
RBC, HCT, MCV, MCH, MCHC, and PLT parameters are flagged. Out of the
particle distribution width data, RDW-CV is flagged with RU and its data are
output.
RDW-SD is flagged with DW and its data are not output. In this instance, MCV
and MCHC are out of Patient Mark Limits.

6) 2C High UD with two or more peaks
RBC, HCT, MCV, MCH, MCHC, and PLT parameters are flagged with RU.
As to particle distribution width data, RDW-CV is flagged with MP and its data
are output, while RDW-SD is also flagged with MP but its data are not output.
7) 3 20%-frequency particle distribution width error
RBC, HCT, MCV, MCH, MCHC, and PLT parameters are not flagged. As to
the particle distribution width data, RDW-CV data are output without flagging,
while RDW-SD data are flagged with DW and their data are not output.
8) 4 Two or more peaks
RBC, HCT, MCV, MCH, MCHC, and PLT parameters are not flagged. As to
the particle distribution width data, RDW-CV data are output with MP flag.
RDW-SD is flagged with MP and its data are not output. In this instance, RDW-
CV is out of Patient Mark Limits.
