Parameter Flags

4.10 SE (Statistical error HGB)

This error flag is related to a statistical check that is made on the HGB parameter. 
The blank and sample is measured 25 times and the SD is calculated from the 
photometer output values. If the SD exceeds a certain limit, the SE flag is dis-
played on the HGB parameter. 

The reason might be:

a)

Bad mixing in the WBC/HGB cuvette.

b)

Air bubbles or large particles in the cuvette.

c)

Heavy mains disturbance (contact your authorized distributor).

In case this warning occurs occasionally, just re-analyze the sample.

4.11

TB (Air bubbles)

This error flag is related to the start detector. If during the raise of the diluent col-
umn in the glass tube, an air bubble should pass the start detector; this warning 
is displayed.

To cancel this error, perform a ‘Prime’ from menu 8.1.

4.12 NM, OM, TM, BD (WBC Differential 

Flags) 

If no WBC Differential is displayed; the following warning flags are valid:

NM'

No Mode'

No significant population was found. There is no valid 3 part WBC population.

OM

'One Mode'

Only one population is found. This flag might be displayed in case of Granulo-
cytosis or Lymphocytosis or if the Granulocytes are collapsed into the Lympho-
cytes (old blood).

TM

'Triple Mode'

There are more than 2 main populations. This flag might be displayed in case of 
Monocytosis, heavy mains disturbance or wrong installation due to poor ground-
ing of the instrument and/or connected printer.

BD

'Bad Distribution'

The LYMF and GRAN population are too overlapped. This flag is displayed if 
the Granulocyte population is collapsed into the Lymphocyte area. The reason 
might be:

•

Old blood or extremely fragile Granulocytes

See 

Limitations

 on page 18.

4.13 RP (Red Cells Present)

This flag is only displayed in case the CA620-CellGuard is used for PLT concen-
trates. If the concentration of Red Blood Cells is > 0.3 in the PLT concentrate, 
both RBC and PLT are flagged with 'RP' to indicate that Red Cells are present 
and that the PLT value may not be correct.
