Section 3 Principles of Operation
Patient, QC, Resistant RBC Mode Flagging (when WOC and NOC are equivalent)
Descriptor/Flag Cause Suggested Action
BAND 1) The BAND flag is triggered if any of
the following conditions are met:
2) The CV% of the neutrophil cluster on
the 0
°
axis exceeds expected criteria.
3) The instrument detects > 12.5% of the
total WBC count as BAND cells
The ratio of suspected bands to mature
neutrophils is >50%
Review a stained smear for the presence of
bands and follow your laboratory’s review
criteria.
NOTE: When bands are present, they are
included in the total neutrophil count.
IG The IG flag is triggered if the following
condition is met:
The instrument detects > or = 3% of the
total WBC count as IG cells
Review a stained smear for the presence of
immature granulocytes and follow your
laboratory’s review criteria.
NOTE: When IGs are present, they are
included in the total neutrophil count.
BLAST The BLAST flag is triggered if the
following condition is met:
The instrument detects > 1% of the total
WBC count as Blast cells
Review a stained smear for the presence of
blasts and follow your laboratory’s review
criteria.
NOTE: When blasts are present, they are
included in the monocyte count.
VAR LYM When the FWBC flag is triggered, the
VAR LYM flag is always set.
In addition, the flag is set if any of the
following attributes apply:
1) Position of the lymphocyte cluster on
the scatter plot is abnormal.
2) The ratio between lymphocytes and
other WBC subpopulations is increased.
3) Lymphocyte count (absolute or %) is
elevated
Review a stained smear for the presence of
variant lymphocytes and follow your
laboratory’s review criteria.
NOTE: When variant lymphocytes are
present, they are included in the
lymphocyte count.
NOTE: This flag may be displayed singly or in
combination with the blast flag. If the
flag is displayed with the blast flag, it
is displayed as VLYM/BLAST.
RBC MORPH One or more of the following parameters
exceeds expected limits:
MCV < 80fL or >100fL
MCH < 25pg or >34pg
MCHC < 29g/dL or >37g/dL
RDW >18.5% Review a stained smear for abnormal RBC or
PLT morphology and follow your laboratory's
review criteria.
