6.3. Morphology Flags

6.3.1. Flags on PLT Distribution curve

The PLT Histogram has 128 channels between 2fl and 30fl. A mobile Threshold (Positioned to 25fl
by default) moves according to the Microcyte population present in the Platelet analysis area.
The PLT flags are as followed:
1- An excessive presences of cells to the right of the Threshold area (25fl) will trigger the «MIC»
(Microcytes) flag. The Mobile threshold looks for a valley between the (25fl standard value) and 18fl.
2- When there is No valley between PLT and RBC populations, a reject PLT (*) flag is triggered. PLT
results are not reliable and must be verified by a Manual Platelet Count.
3- If the number of particles between 18fl and 25fl are too high, the «SCH» (Schizocytes) flag will
be triggered. Suspected abnormalities include:
◆Presence of Schizocytes
◆Presence of Platelet aggregates: Verify the Platelet results on a stained blood smear.
4- The «SCL» (Small cells) flag indicates the presence of small cells in the 2fl to 3fl zone. The PLT
results may be reported as (---) and there may also be no PLT Histogram.

6.3.2. Flags on WBC Distribution curve

The
the operator to the possible presence of pathological cells, abnormal volume distribution histo-
grams, or abnormal elevated populations such as the excessive presence of Eosinophils and
Basophils.
1- Flag «L1» indicates an abnormal number of cells, in comparison with the Lymphocytes, in the
(30fl to 60fl zone). The pathological elements which may be found in this area will include:
◆Platelet aggregates
◆Nucleated Red blood cells
◆Atypical Lymphocytes
This flag corresponds to the number of cells counted in the first (5) channels, out of the total num-
ber of Lymphocytes.
2- The «M2» flag indicates an excessive number of cells in the (130fl to 160fl zone). The Patholog-
ical elements which may be found in this area will include:
◆Lymphoblasts
◆Myelocytes
◆Abnormal Lymphocytes
◆Basophilia (too many basophils)
This flag corresponds to the number of cells counted in the detection zone in comparison to the
total number of Granulocytes.
3- The «G1» flag indicates an excessive number of cells in the (160fl to 220fl zone). The patholog-
ical elements which may be found in this area will include:
◆Eosinophilia (too many Eosinophils)
◆Myelocytes
