Problem Probable Cause and Solutions
If Blood, Question
Data Optical measurements indicate that the CO-ox results should be
reviewed. A question mark (?) is printed next to the CO-ox
results on reports.
Results may still be clinically valid. When reporting CO-ox
results, consider the patient’s history and clinical condition to
determine acceptability of results.
To troubleshoot an If Blood, Question Data message,
determine whether the problem is with the sample type, the
patient sample, or the system.
NOTE: When analyzed as a patient sample, aqueous materials
with dyes cause the If Blood, Question Data message to appear.
1. Ensure that you analyzed a patient sample, not a QC or
calibration sample. Ensure that the patient sample is free of
clots and unidentified interfering substances.
2. If the problem is not with the sample type, analyze the
sample again.
3. If the message reappears, perform a pH/lytes one-point
calibration to zero the CO-oximeter
If the calibration . . .
is successful
is not successful
Then . .
go to step 5.
repeat the pH/lytes one-point
calibration two two more
times.
