Section 3
Patient, QC, Resistant RBC Mode Flagging (when WOC and NOC are equivalent)
Descriptor/Flag Cause Suggested Action
DFLT(NLMEB) One or more of the following conditions
are true:
1) Fragile cells may be present. (When
the FWBC flag is triggered, DFLT
(NLMEB) flag is always set.)
2) There are too few cells to calculate
the differential.
3) The mono-poly population is not well
separated.
NOTE: There are four different DFLT
flags: (NLMEB), (NE), (LM), and
(B).
(N=Neutrophils, L=Lymphocytes,
M=Monocytes, E=Eosinophils,
B=Basophils)
If the DFLT (NLMEB) flag is accompanied by
the FWBC flag, repeat in the FWBC mode.
If the DFLT (NLMEB) flag is accompanied by
the RRBC flag, repeat in the RRBC mode.
Review scatterplot for clear separation of cell
cluster.
Review a stained smear to verify the
differential values.
DFLT (NE)
or DFLT (LM)
or DFLT (B)
or DFLT (LB)
The letters in parentheses indicate which
WBC subpopulation or group of
subpopulations is suspect. The DFLT
flag may be due to the presence of
abnormal cell clusters that the
instrument cannot reliably discriminate
among WBC subpopulations. Thus, a
default threshold is selected.
Review scatterplot for clear separation of cell
cluster.
Review a stained smear to verify the
differential values.
