The result falls above the reportable
range of the test.
If an ACT result is displayed as >1000,
the result should be reported as “greater
than 1000 seconds.”
<
The result falls below the low end of the
reportable range of the test.
If a pH result is displayed as <6.5, the
result should be reported as “less than
6.5.”
<>
This result is dependent on another test
that has been flagged.
The <> flag will also be displayed for
TCO
2
, pH, PCO
2
, HCO
3
, anion gap, base
excess, and sO
2
if the TCO
2
is <1 or >80
mmol/L. Because the values outside this
range are essentially non-physiological,
the TCO
2
range check is used as an
additional quality check on the validity of
the underlying pH and PCO2 results.
If a sodium result is displayed as >180,
the calculations for potassium, chloride,
BUN/Urea and hematocrit, which depend
upon the sodium measurement, will be
flagged < >.
The result is above the high action range. If the action ranges for potassium are 3.2
and 5.5, a result of 6.0 will be displayed
as 6.0 .
The result is below the low action range. If the action ranges for potassium are 3.2
and 5.5, a result of 3.0 will be displayed
as 3.0 .
***
The signals from a particular sensor
are uncharacteristic. Uncharacteristic
signals can be caused by a compromised
sensor or by an interferent in the sample.
This flag also appears for any test
dependent on another test which is
flagged with stars.
The sample should be retested using
another cartridge.
If the stars reappear, refer to the
troubleshooting paragraph in this section
of the manual.
