1.2.3 Reagents
Only reagents recommended by
DIATRON MI Ltd.
should be used with the analyzer,
otherwise accuracy cannot be guaranteed.
Diluent:
Isotonic saline solution used to dilute whole blood
specimens and to rinse the fluidic system between
measuring procedures.
Lysing reagent:
Used to create hemolysate for 3-part WBC
differential and for total WBC and HGB.
EOS Reagent:
A selective reagent similar to the lysing reagent, but
its feature is leaving EOS cells intact, and helping
EOS population definition. Needs thermal
conditioning internally for selective effect.
BAS Reagent:
A selective reagent similar to the lysing reagent, but
its feature is leaving BAS cells intact, and helping
BAS population definition. Needs thermal
conditioning internally for selective effect.
Cleaner:
Used in cleaning process of the fluidics.
1.2.4 Technical Operation
As
Abacus junior 5
is a fully automated instrument, operation requires
minimal training or technical support. Operator interaction is reduced to the following:
•
Perform
a
Blank Measurement
in case the instrument is left idle for a long time
•
Enter sample and/or patient data
•
Insert sample into sample holder for analysis
•
Print results either one-by-one, or by selecting records from the database
•
Perform a simple weekly maintenance, as described later in this manual.
1.2.5 Calibration and Quality Control
Abacus junior 5
arrives to your laboratory factory-calibrated and ready to
use. However, calibration needs updating whenever you find that the results have
slightly changed, a different, or a new control material is used. With each control
material you receive to be used with the instrument, you will find a control sheet
listing the parameters the instrument should match. Perform these calibrations as
explained in a later chapter.
Quality Control is used to check proper calibration and performance of the analyzer.
Running these samples should happen on a regular basis, as also explained in a
later chapter.
