6.4 BETWEEN-SPIN TIME DELAY FOR
ACCUTUBES
Since possible exposure of blood samples to
heat buildup in the centrifuge rotor compartment
can adversely affect cell layering, wait at least
3 minutes between successive spins if the ambient
temperature is between 68°-90°F (20°-32°C). If
the ambient temperature is between 90°-98°F
(32°-37°C), a 15 minute wait period is required to
allow for sufficient cooling of the rotor. Between
each spin, be sure the rotor cover is removed and
the rotor is empty.
6.5 FILLING ACCUTUBES WITH VENOUS
BLOOD
The QBC pipetter must be modified to draw 70 µL
of sample when it is used for filling AccuTubes
with venous blood. Install the AccuTube spacer by
snapping the spacer over the plunger stem of the
pipetter. The spacer limits the stroke of the plunger
to an aspiration volume of 70 µL.
6.6 ACCUTUBE QUALITY CONTROL
Before testing AccuTube samples, perform a daily
calibration check of the QBC Autoread Plus analyzer
according to the procedures in the package insert
supplied with the Autoread Plus calibration check
rod (Cat. No. 424613).
QBC Hematology Control (Cat. No. 424304) is
available for performance monitoring of AccuTubes.
These controls list assay values for AccuTubes.
Proficiency testing services are also available for
regular performance assessment of your laboratory.
