Probable Cause Corrective Action
The system detected an atypical
response when measuring the
parameter. Analyze the sample again to verify the result.
When this symbol appears for the
hematocrit (Hct) result, it may
indicate that the Hct result was not
reported because sodium (Na

performed.
If Required QC analysis was not performed for
sodium, perform the scheduled QC and then analyze
the sample again.
