Performance Characteristics: Imprecision
A total of 18 runs were performed using multiple samples.
The following estimates of imprecision were obtained by taking 25 aspirations
from each whole-blood sample. Each of the sample selectivity modes was tested
by sampling from opened tubes, and with the manual and automated closed-tube
samplers.

Performance Characteristics: Correlation Data
The performance of the ADVIA 120 Hematology System was compared with the
performance of the Technicon H

normal donors and 70 hospital donors with each sample run in duplicate (n =
260).
