1) Sampling Data - RBC/PLT
In the RBC and PLT columns, cell counts taken every 1 second are displayed.
These cell count displays are for monitoring the occurrence of sudden noise. If
the ratio of the difference between the maximum and minimum cell counts to
the total sampling cell count is outside the specified range, a "Sampling Error"
message (analysis error) will be displayed. The total cell counts displayed are
limited by the display digit to 4-figures. Multiply these values by the number
in parentheses at the bottom of the column to obtain the actual total cell count
value.
2) Analyzed Data
R-MFV : Most frequently occurring value in the RBC distribution in the
RBC X-axis channel. (Unit: fL)
P-MFV : Most frequently occurring value in the PLT distribution in the
PLT X-axis channel. (Unit: fL)
PDW-CV : PLT distribution width (CV method). (Expressed as %)
PCT : Platelet-crit. (Expressed as %)
3) DISCRI.
RBC-LD : The position of Lower Discriminator (LD) for the RBC is
indicated with the bin number between 0 and 49.
PLT-LD : The position of Lower Discriminator (LD) for the PLT is
indicated with the bin number between 0 and 49.
RBC-UD : The position of Upper Discriminator (UD) for the RBC is
indicated with the bin number between 0 and 49.
PLT-UD : The position of Upper Discriminator (UD) for the PLT is
indicated with the bin number between 0 and 49.
4) HGB
SAMPLE : Optical density of A/D-converted sample.
BLANK : Optical density of A/D-converted blank.
5) RBC Counting Time
START : The time period that the ball float in the RBC manometer starts
descending and reaches the Start level. (Unit: seconds)
COUNT : The time period that the ball float in the RBC manometer moves
from the Start level to the Stop level. (Unit: seconds)
6) RBC Temperature
Temperature (°C) of RBC detector.
7) RBC Distribution
This item is marked with a cell size abnormality indicator if the RBC size
distribution is abnormal. Refer to Chapter 10, Section 7.4 Histogram Flags for
the indicators.
8) PLT Distribution
This item is marked with a cell size abnormality indicator if the PLT size
distribution is abnormal. Refer to Chapter 10, Section 7.4 Histogram Flags for
the indicators.
