Performing calibrations
Incorrect results when using Use Old
Calibrations are performed to compensate for changes over time in reagents and in the
measurement systems. Failing to perform calibrations when they are due may lead to
incorrect results.
o Roche recommends performing a QC measurement before you continue working
with the old calibration results.
o In the application definitions, choose On for QC After Cal.
(Utilities > Applications > Laboratory Parameters > Control > QC After Cal)
Accepting calibration results
Calibration results will be used by the system only when you have accepted them.
There can be only one unaccepted calibration result for a test.
If there already exists a not accepted calibration for a test and you place another cali-
bration order for this test, the order will be blocked.
