Quality Control
It is recommended that the system be controlled using ADVIA TESTpoint
Reticulocyte Controls. These controls are intended to be integrated into a clinical
laboratory’s own quality control program and procedures.
Control materials should be assayed:
•
At the beginning of each shift or at some other interval chosen by the
laboratory.
•
After a reagent lot number change.
•
After replacement of any part or component of the analytical module that
may affect analytical performance.
As an option, laboratories may run a retained patient sample periodically to
monitor performance trends.
