For Capillary Blood Samples
Touch the collection tip of the STAR Tube to the sample while filling. The tube should be kept hori-
zontal or slightly inclined. Figure 14 shows a capillary blood sample.
For Venous and Capillary Blood Samples
Fill the QBC StaR Tube between the black fill lines. Blood must always be filled to at least the
first black line. This results in a blood volume of between 65 and 75 microliters. The instrument
automatically detects if the fill volume is correct.
mix the tube
Rock the QBC StaR Tube back and forth at least four times to mix the blood with the acridine
orange coating. Do not allow the blood to touch the white plug at the end of the tube.
Note: allowing the blood to flow from the collection end toward the plug end of the tube and back
is equal to one rock.
