5.3.8. WBC balance
During the initial count of the WBC’s in the WBC/BASO chamber, a second WBC count is per-
formed from the injected volume through the LMNE optical flowcell.
The two counts are compared. If the difference between the LMNE and WBC/BASO counts are
higher than the defined threshold, (
depending on the quantity of cells measured ), a LMNE+
or a LMNE- flag will be generated based upon the following conditions:
◆ The WBC count is within 0 and 2501:
If the WBC LMNE count is 50% higher than the WBC BAS count, a LMNE+ flag will be
generated.
If the WBC LMNE count is 50% lower than the WBC BAS count, a LMNE- flag will be
generated.
◆ WBC count is within 2501 and 8000:
If the WBC LMNE count is 20% higher than the WBC BASO count, a LMNE+ flag will be
generated.
If the WBC LMNE count is 20% lower than the WBC BASO count, a LMNE- flag will be
generated.
◆ WBC count is higher than 8000:
If the WBC LMNE count is 15% higher than the WBC BASO count, a LMNE+ flag will be
generated.
If the WBC LMNE count is 15% lower than the WBC BASO count, a LMNE- flag will be
generated.
The WBC BAS channel is considered as a reference and is used to calibrate the WBC LMNE
channel. The calculated ratio between the two channel calibration coefficients is stable (ex-
cept during technical intervention). In any case it is the WBC BAS result that is reported.
The WBC balance flags will appear in the « Analyzer alarm » area.
The WBC balance flags (LMNE+ and LMNE-)shall not be triggered if and only if:
◆ The test selected is «CBC»
◆ The WBC Balance option is not activated. (The WBC Balance can be enabled or dis-
abled by an approved ABX Service Technician). Contact your local ABX Technical Ser-
vice Representative for selection of this option.
These flags are associated with an (!) on all differential parameters (% and#).
