System Specifications Chapter 4
Accuracy
The CELL-DYN 3000 system can be calibrated to agree with reference
values within the allowable calibration ranges. Both modes of operation,
Open and Closed (CS and SL) may be calibrated. Thus, it is possible to
compensate for differences between modes due to differing aspiration
pathways or operational sequences. When each mode is properly
calibrated according to the directions given in this manual, bias between
the modes is clinically insignificant.
Accuracy specifications are determined by correlation to reference values
obtained from comparison analyzers or analysis by reference
methodology. Samples that are used for correlation studies should not
display any suspect parameter flags.
