Precision (sample mode: micro sample)
“Repeatability (S
R
)” and “Intermediate precision (S
I
)” were determined using the
cobas b 123 POC system for 10 days.
The mean value is the measured value of the corresponding parameter for which S
R
and S
I
are representative or have been determined.
Tonometered whole blood Whole blood was tonometered at 37°C with high-precision gas mixtures.
