Operating Instructions Chapter 5
The numbers on the X-B SETUP Screen shown in Figure 5.7 correspond
to the following numbered options:
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 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.
NOTE: The default (preassigned) Target Values on the
X-B SETUP Screen shown in Figure 5.7 are not Dr. Bull's
Target Values. Dr. Bull's Target Values are included in the X-B
Analysis section of Chapter 7, Quality Control .
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 Chapter 7,
Quality Control , of this manual.
