Resistant RBC and QC Modes
Descriptor/Flag
Cause
Suggested Action
(NOC)
WBC
RRBC/NRBC
DFLT (NLMEB)
WOC > NOC in the Resistant RBC cycle
(NOC is selected as WBC count.)
NOTE: Higher WOC is due to unlysed
RRBCs. Lymphocyte count is
corrected by adding the
difference between WOC and
NOC to the lymphocyte count.
Review a stained smear to determine the
cause of the interference (NRBC and/or
unlysed RRBCs).
Verify the WBC value by an alternate method
according to your laboratory’s protocol.
(WOC)
WBC
RRBC/NRBC
NOC > WOC and high stroma
interference in the Resistant RBC cycle
(WOC is selected as WBC count.)
Review a stained smear to determine the
cause of the interference (NRBC and/or
unlysed RRBCs).
Verify the WBC value by an alternate method
according to your laboratory’s protocol.
(WOC)
WBC
NRBC
NOC >WOC, low stroma interference,
and %L<60% in the Resistant RBC cycle
(WOC is selected as WBC count.)
Review a stained smear for the presence of
NRBCs.
NOTE: If NRBCs are present, report WOC for
WBC count.
Confirm WBC by an alternate method.
(NOC)
WBC
FWBC
VAR LYM
DFLT (NLMEB)
NOC>WOC, low stroma interference,
and %L>60% in the Resistant RBC
cycle.
(NOC is selected as WBC count.)
NOTE: Lymphocyte count is corrected
by adding the difference
between WOC and NOC to the
lymphocyte count.
Review smear to confirm Lymph count and
presence of fragile WBCs.
Fragile WBC Mode

Cause
Suggested Action
(NOC)
FWBC
VAR LYM
DFLT (NLMEB)
In the Fragile WBC cycle, the FWBC flag
is always displayed along with the DFLT
(NLMEB) flag.
(NOC is selected as WBC count.)
Review smear to confirm Lymph count and
presence of fragile WBCs.
