Quality Control
Introduction
The CELL-DYN® 3000 offers several quality control options to monitor
and validate instrument performance. The options are:
X-B Analysis—Bull’s moving average program applied to the
RBC indices
20 QC Files—Statistical and graphical analysis of the data in each
file to calculate the mean, standard deviation and coefficient of
variation
Westgard Rules—A multi-rule system applied to the data in each
of the QC files
The options may be used independently or in combination at the
operator’s request. Each option is discussed in detail in the Quality
Control Guide section of this chapter.
The first section of this chapter describes the functions of the keys in the
QC MENU. Interpretation of the data is discussed in the Quality Control
Guide.
