2. Patient Quality Control (XB)
The (XB) Patient Quality Control is used to detect any change in the quality of results by use
of patient data only. This data monitoring is performed without any user intervention and
can be applied to a set of 9 parameters (WBC, RBC, HGB, HCT, RDW, PLT, MCV, MCH, MCHC) or
3 parameters (MCV, MCH, and MCHC). The operator makes the selection of parameters based
on their own population studies (See Section 5,
3.2. XB options , page 5-11).
The XB data can be processed as follows:
All the analyses associated to a patient ( analysis that is not associated with a Calibrator or a
Quality Control blood ) which does not have any “Reject” and/or “DIL” flags, and an RBC and
HCT result within the clinical life sustaining categories. which have neither reject, nor DIL
flag, a RBC result higher than 100.10
3
/mm
3
and HCT higher than 0,7%, are archived with
their flags.
When a total of 20 results are archived, an XB batch is computed.
The batch data commutated, is the mean result for all 20 analyses contained in that specific
batch.
The date of computation of the batch values is noted as the «batch date».
An (XB) alarm occurs when the calculation of the last batch shows a point located outside
of the limits set by the operator (see
2.5. XB limits, page 3-19). The operator can disable
this alarm.
A maximum of 60 batches can be stored within the software.
