Additional
messages
This table provides an interpretation of additional messages that may appear.
Message Interpretation Corrective Action
I/A Parameter is inactive. Turned off
by user.
No action required.
L/O Parameter locked out due to QC
results outside acceptable limits.
Perform a successful QC
measurement or deactivate the
QC lockout feature.
N/A Not applicable. Appears in the
Hct field when Other Fluids is
selected for sample type.
If Hct results are desired, repeat
the analysis selecting any sample
type other than Other Fluids.
N/D Parameter not derived because
measurement parameters
necessary for this calculation are
not available.
Activate necessary measured
parameters or select necessary
measured parameters for
reporting.
N/E No endpoint. Stabilization criteria
not met for one or more
parameters during sample
measurement or calibration.
No endpoints suggest air in the
measuring chamber. Investigate
possible sources of air. Then
perform a manual calibration and
repeat the measurement.
N/I Not installed. A BG/Hct – only or
Lytes – only sensor cassette has
been installed on a full panel
analyzer.
If all parameters are desired,
install a full panel sensor cassette.
N/R Not reported. This parameter was
not selected for reporting by the
user.
Select all desired parameters from
the parameter profile and repeat
the analysis.
N/C Not calculated. Hct cannot be
calculated due to a failed Na+
calibration
Repeat the calibration. If the
Na
+
failure persists, either continue
testing without Hct or replace the
sensor cassette.
*** Measured parameter value is out
of the analyzer display range.
Evaluate the integrity of the
sample. Perform a manual
calibration and repeat the sample
analysis.
# # # Sensor response is out of the
established response range.
Initiate a manual calibration.
Repeat the sample analysis.
