Measurement parameters
Precision (sample mode: normal)
“Repeatability (S
R
)” and “Intermediate precision (S
I
)” were determined from 2 runs
per day with 2 replicated per run for 20 days using the cobas b 123 POC system.
The mean value is the measured value of the corresponding parameter for which S
R
and S
I
are representative or have been determined.
