Performance characteristics and limitations of the method
A manual differential analysis of white blood cells cannot be
accomplished with EIGHTCHECK-3WP-N, EIGHTCHECK-3WP-
L and EIGHTCHECK-3WP-H.
The PRP (platelet rich plasma) method to assay the platelet count
cannot be accomplished with EIGHTCHECK-3WP-N,
EIGHTCHECK-3WP-L and EIGHTCHECK-3WP-H.
Traceability of control materials
The mean assay values (range) of EIGHTCHECK-3WP-N,
EIGHTCHECK-3WP-L and EIGHTCHECK-3WP-H are derived
from replicate analyses on whole blood calibrated instruments using
the reagents recommended by the equipment manufacturer.
The measuring results for EIGHTCHECK-3WP-N, EIGHTCHECK-
3WP-L and EIGHTCHECK-3WP-H should be within the relevant
expected range.
The expected ranges listed represent estimates of inter-laboratory
variation, which is usually accounted for by instrument calibration,
maintenance and operating technique.
For this reason, the assay values given are guidelines only used for
the control of the measuring system and are not absolute assays for
calibration.
Disposal
Expired EIGHTCHECK-3WP-N, EIGHTCHECK-3WP-L and
EIGHTCHECK-3WP-H should not be disposed in general waste.
Disposal procedures should meet the requirements of all applicable
local regulations.
