FUNCTIONAL DESCRIPTION
Sysmex KX-21 Operator’s Manual -- Revised October 1998 9-23
1) 1A Histogram with high frequency for LD
RBC, HCT, MCV, MCH, MCHC, PLT, and particle distribution width data
parameters are flagged with RL. MCV and RDW-SD exceed the upper Patient
Mark Limits, and MCHC falls below the lower Patient Mark Limits.

2) 1B High frequency for LD with 20% particle distribution width error
RBC, HCT, MCV, MCH, MCHC, and PLT parameters are flagged with RL.
Of the particle distribution width data, RDW-CV is flagged with RL and its data
are output. RDW-SD parameter is flagged with DW and its data are not output.
3) 1C High LD with two or more peaks
RBC, HCT, MCV, MCH, MCHC, and PLT parameters are flagged with RL.
RDW-CV is flagged with MP and its data are output, while RDW-SD is flagged
with MP but its data are not output.
4) 2A Frequency high for UD
RBC, HCT, MCV, MCH, MCHC, PLT, and particle distribution width data
parameters are flagged with RU. In this instance, flags to indicate that their data
are out of Patient Mark Limits are added to MCV, MCHC, and RDW-SD.
