Calibration Procedures
Pre-Calibration Procedures
Overview
The
Pre-Calibration Procedures
in this subsection verify proper instrument
performance to ensure a successful calibration. These steps should be completed
just prior to beginning the calibration procedure itself. If problems are detected
during these checks, DO NOT ATTEMPT TO CALIBRATE THE INSTRUMENT.
If necessary, CALL THE ABBOTT HEMATOLOGY CUSTOMER SUPPORT
CENTER FOR ASSISTANCE. After the problems have been resolved, repeat the
Pre-Calibration Procedures to verify proper performance.
NOTE:
Instrument calibration, including the pre-calibration procedures, should
be completed without interruption.
Calibration Guidelines
1. Always perform the Daily, Weekly and Monthly scheduled maintenance as
directed in
before calibrating the
instrument. Instrument cleanliness is essential for accurate calibration.
Therefore, each laboratory should perform any additional maintenance
according to its requirements.
2. Use only recommended CELL-DYN reagents.
3. Verify the precision for the Open and Closed Modes prior to calibration as
directed in the Pre-Calibration Procedures Checklist.
NOTE:
If necessary, refer to the directions for customizing the display and
printout of a QC file given in
;
4. Select and process all whole blood samples according to the requirements
given in
Fresh Whole Blood Requirements
later in this section.
5. Try to obtain a sufficient amount of sample (calibrator or fresh whole blood)
so that the same sample can be used for precision check, calibration in Open
and Closed Modes, and confirmation in Open and Closed Modes. If sufficient
sample is not available, use a different sample for precision check.
6. Be certain that all samples used are brought to room temperature and mixed
well before aspiration.
7. Be certain that the technologist performing the calibration has read and
understands the information contained in the package insert for the calibrator.
8. Be certain that the technologist performing the calibration has read and
understands the calibration procedure(s) and the appropriate overviews
described in this manual.
9. Confirm that reagent containers are at least one third full. Replace them as
necessary.
