ensure the anticoagulated character depending on agglutination and reanalyzed only for
the platelet count. The final PLT result must be corrected for the sodium citrate dilution
effect. However, these platelet clumps do trigger flags L1, LL and LL1.
MPV (Mean Platelet Volume)
:
◆
Giant platelets
that exceed the upper threshold of the Platelet parameter may not be
counted as platelets. Consequently, these larger platelets will not be included in the in-
strument’s calculation of Mean Platelet Volume.
◆
Very small erythrocytes
(microcytes), erythrocytic fragments (Schizocytes) and white
blood cell fragments may interfere with the proper counting and sizing of Platelets.
◆
Agglutinated erythrocytes
- May trap Platelets, causing an incorrect MPV result. The pres-
ence of agglutinated erythrocytes may be detected by observation of abnormal MCH and
MCHC values and by careful examination of the stained blood film.
◆
Chemotherapy
- May also affect the sizing of PLTs.
Blood samples collected in EDTA will not maintain a stable Mean Platelet Volume.
Platelets collected in EDTA swell depending on the time post-collection and storage
temperature.
LYM# (Lymphocyte count absolute value), LYM% (Lymphocyte percentage
):
◆
The Lymphocyte count is derived from the WBC count. The presence of erythroblasts, cer-
tain parasites and erythrocytes that are resistant to lysis may interfere with an accurate
LYM count. Limitations listed for the WBC count pertain to the LYM # and % counts as well.
MON# (mononuclear cell count absolute), MON% (Mononuclear percentage)
:
◆
The mononuclear cell count absolute is derived from the WBC count. The presence of large
lymphocytes, atypical lymphocytes, blasts and an excessive number of basophils may in-
terfere with an accurate monocyte count.
◆
Limitations listed for the WBC count pertain to the MON # and % counts as well.
NEU# (neutrophil count absolute), NEU% (Neutrophil percentage)
:
◆
The neutrophils cell count is derived from the WBC cell count. The excessive presence of
eosinophils, metamyelocytes, myelocytes, promyelocytes, blasts and plasma cells may in-
terfere with an accurate neutrophils count.
EOS# (Eosinophil cell count absolute), EOS% (Eosinophil percentage)
:
◆
The eosinophil cell count is derived from the WBC cell count. The presence of abnormal
granules (degranulated areas, toxic granules...) may interfere with the eosinophil count-
ing.
BAS# (Basophil cell count absolute), BAS% (Basophil percentage)
:
◆
The Basophil cell count is derived from the WBC cell count.
