Quality Control
Revised July 2012
9. Quality Control
The reliability of this instrument and reagents is monitored by quality
control. By use of control blood or control materials the stability of
the measured value is monitored over a certain period of time, and
problems can be detected early or prevented.
A quality control should be performed:
• Before analyzing samples
• After replacement of the reagent
• After maintenance
• If there is any doubt about the accuracy of the analysis values
• As required by regulation(s)
Control blood is analyzed in whole blood mode for quality controls.
9.1 Control material
The control materials, EIGHTCHECK-3WP-N(Normal),
EIGHTCHECK-3WP-L(Low level) and EIGHTCHECK-3WP-
H(High level) are used. These are equivalent to Low, Normal and
High level.

EIGHTCHECK-3WP-L 1.5 mL × 12 vials
4.6 mL × 12 vials
EIGHTCHECK-3WP-H 1.5 mL × 12 vials

Intended purpose
Control blood material is used to test the precision and accuracy of
automated and semi-automatic hematology analyzers. Do not use
EIGHTCHECK-3WP-N, EIGHTCHECK-3WP-L and
EIGHTCHECK-3WP-H for the calibration of the system.
• Do not use any other control material than
EIGHTCHECK-3WP-N, EIGHTCHECK-3WP-L and
