◆
Platelet agglutination
- Clumped platelets due to poor collection techniques or platelet
satellitosis caused by EDTA activation of immunoglobulins may cause a low platelet count and/or
an elevated WBC count.
◆
These types of specimens should be re-collected in sodium-citrate anticoagulant and re-analyzed
"For Platelets Only"!
3.3.10. MPV (Mean Platelet Volume)
◆
Giant platelets
- That exceed the upper thresholding of the platelet channels, may not be counted
as platelets. Consequently, these larger platelets will not be included in the instrument
'
s
calculations of the mean platelet volume.
◆
Agglutinated red blood cells
- May trap platelets, causing an erroneous MPV result. The presence
of aggultinated erythrocytes may be detected by observing abnormal MCH and MCHC values and
by careful examination of a stained blood smear.
◆
Very small erythrocytes
- Microcytes, erythrocyte fragments - schistocytes and white blood cell
fragments may interfere with the proper sizing and counting of the platelets.
◆
Chemotherapy
- May also affect the sizing of platelets.
3.3.11. LYM# (lymphocyte count absolute value)
◆
The lymphocyte count is derived from the WBC count. The presence of nucleated red blood cells
(NRBC), certain parasites and erythrocytes that are resistant to the lysing action, may interfere with
an accurate LYM# count. Limitations listed for the WBC count pertain to the LYM# count as well.
3.3.12. LYM% (lymphocyte percentage)
◆
The lymphocyte percentage is determined, according to the WBC count and the number of
lymphocytes. The presence of NRBCs, certain parasites and erythrocytes that are resistant to the
lysing action, may interfere with an accurate LYM% count. Limitations listed for the WBC count
pertain to the LYM% count as well.
3.3.13. MON# (monocyte count absolute value)
◆
The mononuclear cell count is derived from the WBC count. The percentage of large lymphocytes,
atypical lymphocytes, lymphoblasts and an excessive number of basophils may interfere with an
accurate monocyte count.
3.3.14. MON% (monocyte percentage)
◆
The monocyte percentage is determined, according to the WBC count and the number of
monocytes. The presence of large lymphocytes, atypical lymphocytes, lymphoblasts and an
excessive number of basophils may interfere with an accurate monocyte % count.
3.3.15. GRA# (granulocyte count absolute value)
◆
The granulocyte cell count is derived from the WBC count. The excessive presence of eosinophils,
metamyelocytes, myelocytes, promyelocytes, myeloblasts and plasma cells may interfere with an
accurate granulocyte # count.
3.3.16. GRA% (granulocyte percentage)
◆
The granulocyte percentage is determined, according to the WBC count and the number of
granulocytes. The excessive presence of eosinophils, metamyelocytes, myelocytes, promyelocytes,
myeloblasts and plasma cells may interfere with an accurate granulocyte % count.
Blood samples collected in EDTA will not maintain a stable mean platelet
volume. Platelets collected in EDTA will swell with time and temperature
