ANALYTES
Reproducibility
Controls
Within run precision (S
wr
) and Total Precision (S
T
), were determined from 2 runs per day with 2 replicates
per run over a period of 20 days following the CLSI guideline EP5-A2. Typical results for 3 different
control levels are shown below.

Whole Blood
Within-run precision in whole blood samples was evaluated at 3 different concentrations on the OPTI
CCA-TS2. The table below shows the Averages, Standard Deviations and % CV calculated from 10
samples for each level.
