Quality control materials and calibration verification materials were analyzed on
the 860 systems. The results are presented here.
Precision on aqueous quality control materials was estimated using fifteen 860
systems. Seventeen runs per instrument were made over a twenty-two day period.
Two replicates of each control level were analyzed in each run.
For glucose, precision on aqueous calibration verification materials was estimated
using fifteen 860 systems. Data from seven to sixteen runs per instrument were
available. The data were collected over a two-month period. Two replicates of each
control level were analyzed in each run.
For lactate, precision on aqueous calibration verification materials was estimated
using fifteen 860 systems. Six runs per instrument were made over an eight day
period. Two replicates of each control level were analyzed in each run.
Table E-29 summarizes the results of the 860 system precision on QC materials.
