Flags 6-15
Myeloperoxidase Deficiency (MPO-D, MO)
Definition
Sample is a weak peroxidase stainer.
This flag is triggered if [%PMN - (%NEUT + %EOS)]
≥
25, the NRBC flag was
not triggered, and there is a valid MN-PMN valley (d/D
≥
0.15).
You must perform a manual differential on samples that trigger the
Myeloperoxidase Deficiency flag.

Perox Cytogram
Baso Cytogram
Because %PMN - (%NEUT
+%EOS) is close to 0, there is no
flag.
By inspection, the sum of the
events in the NEUT (
1
) and EOS
(
2
) areas appears approximately
equal to the count in the PMN
area (
3
).
Perox Cytogram
Baso Cytogram
Because %PMN
−
(%NEUT
+ %EOS) is greater than 25,
the flag is triggered.
By inspection, the sum of the
events in the NEUT (
1
) and
EOS (
2
) areas is much less
than the count in the PMN
area (
3
).
