Operating Your Analyzer
6-15
Parameter flags
If the analysis result is followed by an ”H” or “L”, it means the analysis result has
exceeded the upper or lower limit of the reference range.
If you see *** as opposed to the result, it means the result is either unreliable or out of the
operating range.
If the WBC result is less than 0.5 × 10
9
/L, this analyzer will not perform the differential
analysis and all the related parameter values will be non-numeric (***).
z The result of the background check will not be flagged.
Histogram flags
The system will flag abnormal histograms.
Abnormal WBC histograms will be flagged by one of the markings: R1，R2，R3，R4 and
R
m.
R
1
：indicates abnormality on the left side of the lymphocyte hump and possible presence of
platelets coagulate, large platelet, nucleated red cell, insolvable red cell, protein, lipoid debris
in sample, or electrical noise.
R
2
: indicates abnormality between the lymphocyte hump and the mononuclear area and
possible presence of atypical lymphocyte, original cell in the sample and increased eosinophil
or increased basophil.
R
3
： indicates abnormality between the mononuclear leukocyte and the neutrophilic
granulocytes and possible presence of immature granulocytes, abnormal sub-population in
the sample, or increased eosinophil.
R
4
：indicates abnormality on the right side of the neutrophilic granulocytes hump and
increased absolute number of neutrophilic granulocyte.
R
m
：indicates at least two R flags.
Abnormal PLT histograms will be flagged by one of the markings: P
m
，P
S
and P
L.
P
m
：indicates blur demarcation between the platelet and red blood cell area and possible
presence of large platelet, platelet coagulation, small red blood cell, cell debris or fibrin.
P
S
：indicates excessive small PLTs.
P
L
：indicates excessive large PLTs.
