12 Quality Control
Daily use of quality control (QC) ensures that the ‘Abacus 5’ analyzer is operating optimally. Stable recovery of
standard QC material parameters assures the operator that the ‘Abacus 5’ is operating consistently on a day-to-
day basis and is functioning correctly.
By analyzing control materials on a regular basis, day-to-day reproducibility and general condition of the analyzer
can be monitored. Target values and acceptable (tolerance) ranges for each parameter can be specified for an
unlimited number of QC materials.
Control materials must be used before their expiration date. Always observe the control
manufacturer’s instructions for storage and use. Control materials must be well mixed
before use.
Diatron recommends the use of Diacon 5 controls from Diatron.
The ‘Abacus 5’ analyzer does not limit the number of QC material lots or the number of QC measurement runs
that are stored in the control database. Each QC measurement run is saved to the selected QC material lot.
QC lots can be commercial control materials or a whole human blood sample whose parameter values and ranges
are determined by other means. The advantage of a commercial control material is that is shelf life is much
longer than human blood, allowing control of the analyzer for a longer period of time.
Controls in the ‘Abacus 5’ are processed in manual mode only. To access the QC panel, select the ‘QC’ icon on the
main menu.

Before taking any QC measurements, target values and acceptable ranges must be specified for a QC lot of
control material. Click or tap the ‘Set QC reference’ button to display the Set QC panel.
