8.5.3 Leucocytes Flags
SCATTERGRAM FLAGS:
All the followings flags levels are adjustable in the 20 types of blood (see section 3.4.4).
Number of cells in a zone:
N1 (Noise 1): Presence of platelets aggregate, debris or resistant RBC.
N2 (Noise 2): Presence of platelets aggregate, erythroblast or small lymphocytes.
IC: Presence of Immature Cells (from the mono or polynucleated cells line).
Number of cells located of each side of the threshold:
RL (Right Lymphocytes: Presence of atypical lymphocytes or basophiles.
HL (High Lymphocytes): Presence of basophiles, small neutrophils (without granulations or few
segmented), band cells.
NL (Neutrophils Low): Presence of small neutrophils (without granulations or few segmented), band
cells or hyper basophil monocytes.
NH (Neutrophils High): Presence of giant neutrophils, hyper segmented neutrophils, eosinophils with
few granulations or damaged eosinophils.
These flags may appear if the blood was not store
in good conditions or if it was sampled too
much (more than 10 times).
DIF parameters display rules:
- If one or more DIF parameters (LYC, MON, NEU, EOS or BAS) are following with a star (XXX *) the
sample must be checked on smear.
- Basophiles result must be checked on smear if it is following by a star (XXX *).
