PROPRIETARY INFORMATION

Interval QC is not based on the actual number of samples for
an assay, but is based on the number of samples aspirated on
the FastTrack™ or Sample Carousel. When the "As Needed"
option is selected, QC will not run for an assay if samples were
not run for that assay. When "As Needed" is not selected, the
QC will run for every defined control at the set interval,
whether or not samples are ordered for the assay.
Interval QC for all assays is reset by the instrument being
powered off or when the interval occurs on a different day. In
this example, the system was powered off as part of
SHUTDOWN and the interval for the QC was reset.
For a QC result to be flagged with an "L" or "H" Result Flag,
the mean concentration and SD must be considered. A result is
rounded to the reporting number of decimals for an assay after
comparing the result to the QC range.
The range in the following example is 90 to 100.

99.49

When the result is 90, it is not known if the actual value was
90.001 (no Flag) or 89.999 (L Flag).
