Table 3.4 Specimen Modes
Patient, QC, Resistant RBC Mode Flagging (when WOC and NOC are equivalent)
Descriptor/Flag
NWBC 1) When stroma interference is >1.5% of
analyzed events and there is no
declining WOC kinetic rate.
2) In patients with leukopenia the NWBC
is set when the stroma interference is
>2.5.%
NRBC When stroma interference is >3.0% of
analyzed events and there is no
declining WOC kinetic rate,
or
When the patient is anemic and the
stroma interference is >0.9% of
analyzed events and there is no
declining WOC kinetic rate.
NRBC In addition to the criteria above, if the
WBC number of analyzed events is high or
DFLT (NLMEB) indicates a likely interference in the WBC
count, then the WBC alert and DFLT
NLMEB flags are also given.
RRBC Stroma interference is high and a
WBC declining WOC kinetic rate is detected.
DFLT (NLMEB)
FWBC Stroma interference is low but a
VAR LYMPH declining WOC kinetic rate is detected,
WBC or
DFLT (NLMBEB) Stroma interference is low and there is
no declining WOC kinetic rate, but
WOC>8.0 K/uL and LYM%>80%.

Suggested Action
Review smear for platelet clumps, giant
platelets or low levels of NRBCs and follow
your laboratory's review criteria.
If no other suspect parameter flags are
present, the WBC and differential may be
reported.
Review smear for the presence of NRBCs and
follow your laboratory's review criteria.
Review smear for the presence of NRBCs and
follow your laboratory's review criteria.
Confirm WBC count by alternate method.
Repeat in Resistant RBC Mode.
If flag persists, review for presence of NRBCs
and verify Lymph valve. Confirm WBC count
by alternate method.
Repeat in FWBC mode. NOC result will be
reported as WBC result.
Review smear to confirm lymph count and
presence of fragile WBCs.
