D6 Excessive Noise: Glu Lac
Problem
Corrective Action
The sensor signal
has excess noise.
The patient sample
result for the
affected parameter
is reported as
question result
(-----?).
Correct any reagent problems such as D23 codes before you
attempt to correct this D code.
•
Ensure that the measurement module door was not opened
during analysis.
If door was opened, repeat the sample analysis.
•
Perform a successful calibration (1-point or 2-point).
Refer to
Performing Manual Calibrations
•
If a D6 occurs during sample analysis, repeat the sample.
•
Deproteinize the sample path and condition the sensors.
•
Deproteinizing the Sample Path
•
Check the solution level in the affected measurement sensor
and look for bubbles.
The K
+
, Ca
++
, and Cl¯ sensors should be nearly full. The pH
and Na
+
sensors should be full. If the solution level is low,
refill the sensor.
•
If a D6 occurs for more than one sensor, check the solution
level in the reference sensor and look for salt in the vent hole
and bubbles in the sensor.
•
Clean and refill the reference sensor as needed.
•
Check the sensor contacts and measurement block for salt
buildup.
•
Check behind the sensors for fluid leaks.
•
If salt or leaks are present, clean the sensor with water, dry,
reinstall, and perform a 2-point calibration.
Refer to
Performing Manual Calibrations
•
If the problem persists, replace the sensor.
•
If the problem persists, call for technical assistance.
