system overview
The QBC STar Hematology System is a self-contained, whole blood, automated hematology system.
reported results include hematocrit, hemoglobin, total white blood cell count, combined lymphocyte
and monocyte count, granulocyte count, platelet count, and MCHC. The test can be performed from
either venous or capillary blood specimens. The system is factory preset and user calibration is NOT
required. The system is powered by a universal voltage external power supply that plugs directly into
an aC power source.
The QBC STar Hematology System performs all tests using the QBC STar Tube. The QBC STar
Tube is described below. When the QBC STar Tube is placed into the instrument, it is automatically
centrifuged and analyzed. The results are computed, displayed, and printed on the internal printer.
QbC sTAR blood Collection Tubes
The QBC STar Tube is a two-component device. The tube assembly represents the first component.
It consists of a precision glass QBC Tube and the plastic sleeve that serves as a carrier for the tube. a
cap and float assembly comprise the second component. The float expands the buffy coat region by
a factor of ten. It does this by reducing the cross sectional area of the tube.
The QBC STar Tube is preassembled and consists of the following components :
• 3” long precision bore glass tube with dried coatings of acridine orange, heparin, K
2
EDTa,
potassium oxalate, monoclonal antibody and other reagents
• A vented plug at the end of the tube
• Protective plastic sleeve

Tubes are filled by capillary action with 65 to 75 µL of whole blood. This is the volume when the tube
is filled between the 2 fill lines marked on the QBC STar Tube. The blood can come directly from a
fingerstick or from a lavender top EDTa anticoagulant only. The plug has a vent allowing air to escape
during filling of the tube. The vent closes off when the tube is capped.
after the tube assembly is filled with blood, the blood is mixed and the cap assembly is placed on the
tube. The cap consists of the following components:
• A precision molded plastic float
• A float holder
