Performance Characteristics: Correlation Data

The performance of the ADVIA 120 Hematology System was compared with the
performance of the Technicon H•3 RTC System (x) using whole blood from 60
normal donors and 70 hospital donors with each sample run in duplicate (n =
260).
The following regression statistics were computed using a protocol similar to that
recommended in the NCCLS document EP9-A, Method Comparison and Bias
Estimation Using Patient Samples; Approved Guideline (1995).
