Sample/System Flags; Summary - Siemens ADVIA 2120 Operator's Manual

Sample/System Flags

Summary

Through the use of complex flagging algorithms, laboratory personnel are alerted
to suspected abnormal sample and/or system conditions.
Sample/system flags appear on the Run Screen and the Review / Edit tab.
Whenever such flags are triggered, the user should review the results and take the
action recommended. The following table identifies the sample/system flags that
could be triggered for each test selectivity. The two-letter codes in parentheses
appear on the Sample/System Flag Analysis panel of the Run Screen.
Flag Triggering Criteria
B-SUSP (BC) Events above the upper
MN/PMN threshold on y
axis and in channels 0 to 49
on x axis ≥ 5%
BIFR (BR) Baso Flatness > 2.5
B-NO (NB) Baso % Noise > 10
B-NV (VB) 1. (BASO d/D) < 0.15
2. Flag is not set if there is
WBC agreement (no
WBC-CE flag) and
[(%NEUT + %EOS) -
%PMN] is between 0
and 7.5.
B-SAT (BS) 1. Baso % Saturation > 2.5
2. Flag is not set if there is
WBC agreement (no
WBC-CE flag).
BTO (TB) 1. Baso chamber
temperature is not
between 31.9°C and
34.1°C.
2. Flag is not set if there is
WBC agreement (no
