This section contains two major subsections: Quality Control Menu, and Quality
Control Guide. The Quality Control Menu describes the functions of the keys in the
QC MENU. The Quality Control Guide discusses the interpretation of QC data.
The CELL-DYN 3200 offers several Quality Control options to monitor and
validate instrument performance. The options are:
X-B Analysis —
20 QC Files —
Westgard ® Rules —
The above options may be used independently or in combination, depending on the
operator's preference. Each option is discussed in detail in this section.
Quality Control procedures, both internal and external, allow the operator to verify
the performance of an analytical system. The use of Quality Control procedures in
evaluating both commercial controls and patient samples facilitates the
interpretation of laboratory data to ascertain acceptability of patient results.
The information in this section conforms to Abbott Laboratories' recommended
procedures for Quality Control for all Abbott hematology instruments. It is
recommended that these guidelines be incorporated into the procedure manual for
your laboratory. In addition, refer to your laboratory's Standard Operating
Procedures and/or Quality Assurance plan for additional Quality Control
requirements.
