X-B Setup Menu
The
[X-B SET UP]
key is used to select the
X-B SET UP
screen. (See Figure 5.7.) This
screen is used to enter upper and lower acceptance limits, target values, and action
limits for the X-B Moving Average QC Program for both the WBC and RBC
parameters. The following soft key labels are displayed when the
[X-B SET UP]
key
is pressed:
TURN X-B RBC ON/
(The key alternates between the selections.)
TURN X-B RBC OFF
TURN X-B WBC ON/
(The key alternates between the selections.)
TURN X-B WBC OFF
PRINT
RETURN
The following options are available on the
X-B SET UP
screen shown in Figure 5.7:
1.
LOWER/UPPER LIMITS
The
Lower and Upper Limits
determine which patient results will be used
in the X-B Moving Average calculation. Results that fall outside these limits
are automatically excluded from the X-B calculations. These limits should be
set widely to exclude grossly abnormal samples (such as background counts)
that would bias the calculation but should include at least 95% of the patient
results.
2.
TARGET VALUE
The
Target Value
for X-B Analysis is similar to the assay value for a
commercial control. It is derived from the patient population that is analyzed
on the instrument.
3.
ACTION LIMIT
The
Action Limit
is the acceptable limit of variation around the target value.
NOTE:
The X-B Program is discussed in detail in
