Recovery
The value obtained when the final absorbance of each of
the replicates used is multiplied by the determined
Calibration Factor. This is the value that would be obtained
if the calibrator was run as a sample using this calibration.
The closer the recovery of the calibrator is to the setpoint,
the better the calibration is.
Calibration Error Log
The fields listed below categorize information about a
failed calibration. Multiple errors are shown here for any
chemistry failure. The errors should correlate with any of
the asterisked (*) fields listed within the calibration report.
This section of the report appears only when a calibration
fails.
• Reagent – Identifies the failed chemistry.
• Lot Number – Identifies the lot number of the reagent
which failed calibration.
• Serial Number (S/N) – Identifies the serial number of
the specific cartridge which failed.
• Cuvette – Identifies the cuvette in which the specific
replicate failed.
• Condition – In the event that an error occurs, an asterisk
(*) appears next to the value which is out of
specification. The corresponding error flag will print in
this field. Only those errors that FAIL the calibration
will print.
Value – Shows the absorbance value that failed calibrator
or reaction limits.
• Magnitude – This is an indication of the severity of the
failure. Depending on the error, the magnitude may
reflect the actual value of the error or it may show the
absolute difference between the limit and the actual
value. Likewise, the magnitude may not be applicable to
the error which has occurred. If this is the case, no value
will appear under this field.
