23 ISE Measurement Unstable. The mV values from the electrode are not stable. The following problems
may have occurred: - Air bubbles in measuring segment. - One or more sealing rings is missing or
damaged. - Electrode has not been serviced. - Expiry period of the electrode has been exceeded or the
electrode is damaged. - Preamplifier is not working properly. (F3)
1 Not enough readings in kinetic range for calc mode Kinetic or Kinsearch. (F3)
50 The value is below the lower limit of a limit control. (F4)
2 Low Activity. The absorbance change during measurement doesn't reached the accepted limit, i.e . the
reaction has taken off too slow.
24 The intensity obtained in the parallel or perpendicular measurement is insufficient. (F3)
4 The result is lower than the measurable test range. (F3)
26 The sensor could not detect a calibrator. ISE Calibrator bottles are not available or the tubing is blocked
or leaking. (F3)
25 The sensor could not detect any liquid. Either the liquid has not been pipetted, the pipetted sample was
lipemic, or the ISE tubing was blocked. (F3)
27 Unable to calculate the kinetic change. Either change is not stable (Kinsearch) or "non-existent"
(Kinetic). The first and last part of the reaction have very different slopes. (F3)
0 No Flag.
30 Too many outliers occurred in the parallel or perpendicular FP measurement. Air bubbles in the sample
or electronic noise may be the cause. Recommended action: Repeat the measurement with a sample
free of bubbles; Inform Roche Service is flag appears again. (F3)
31 The parallel measurement was higher than the perpendicular measurement. Recommended action:
Repeat the measurement. Inform Roche Service if flag appears again. (F3)
44 Westgard rule 5: Difference between two consecutive control values is greater than 4 SD. Action: rerun
with fresh control; if flag repeats, check calibration, reagent (age) and the course of the reaction. (F4)
47 Westgard rule 1: one control value deviates from the mean (in either direction) by more than 2 SD but
less than 3 SD. (F4)
46 Westgard rule 2: one control value deviates from the mean (in either direction) by more than 3 SD. (F4)
39 Westgard rule 6: Ten consecutive values appear on the same side of the mean. (F4)
45 Westgard rule 3: Two consecutive control values deviate from the mean (in the same direction) by more
than 2 SD but less than 3 SD. (F4)
43 Westgard rule 4: Four consecutive control values deviate from the mean in the same direction by more
than 1 SD. (F4)
42 Precision rule: Seven consecutive values decreased. (F4)
41 Precision rule: Seven consecutive values increased. (F4)
40 Precision rule: Seven consecutive values appear on the same side of the mean. (F4)
63 Result obtained after a repeated run. (F1)
37 No end of calibrator segment detected. It takes too long for a calibrator segment to reach the electrode
assembly. This may be due to the lack of calibrator or the tubing may be blocked or leaking. (F3)
36 No end of sample segment detected. It takes too long for a sample segment to reach the electrode
assembly. The tubing may be blocked or leaking. (F3)
14 Result calculated using an erroneous or corrected calibration which has not been accepted. (F1)
70 Result calculated using a postponed calibration which has not been accepted. Note: Postponing a
calibration may lead to erroneous results Action: Check carefully the results - Repeat calibration if
necessary.
35 Result (or a replicate) is erroneous or corrected. Result has not been accepted. Recommended action:
Check results reaction curve to establish the cause of the deviation; repeat sample measurement. (F1)
