QC Backup
Introduction
The QC Backup function saves the control information and QC View data on a floppy
diskette for future review. The archived data can be reviewed in the following
functions:
• Review Control
• QC File List
• QC Log
• QC Summary
• QC Chart
• QC Print
The control information consists of the inputs used to define a control. (Refer to
Defining a Control in this chapter.)
The QC View data consist of the result date, result value, QC rule flags, deleted data
point date, action log comment, deleted result, operator ID, and reagent lot number.
QC results that are archived on floppy diskettes may be deleted from the QC Result
database on the hard disk. The cumulative statistics are not affected by this deletion.
Why Perform Routine QC Backup
The IMMAGE 800 database can store up to 35,000 QC results from 999 QC files.
Upon exceeding 999 QC Files, a pop-up window appears notifying the operator that
the QC database is full. Some QC Files must be deleted to make room for new QC
Files. Upon reaching 35,000 QC results, a result associated with a File Number
overwrites the oldest result related to the File Number. If there are no results
associated with the File Number, the new result is not stored. A message appears
notifying the operator that the new result was not saved.
To avoid loss of QC results, it is necessary to perform routine QC Backup. The
interval will vary depending on the number of controls run.
The system also monitors the database and reports the remaining hard disk storage
space for QC. This is displayed on the Quality Control screen just below the menu
toolbar. Backup should be considered when less than 5% of QC storage space
remains.
