Performing a proficiency test measurement
NOTICE
To verify the accuracy of measurement values, perform proficiency testing.
Roche recommends that you perform proficiency testing to verify the accuracy of
measurement values. Proficiency test materials may contain interfering components,
missing or insufficient buffer systems, and differences in ionic strength and diffusion
potential compared to biological samples, and may affect the accuracy of
measurement values.
NOTICE
The cobas b 123 POC system can measure proficiency test or EQA materials.
However, results are not obtained if they are outside of the measuring range or
outside of the system specifications. This may occur because the concentration of
these materials is unknown, or the materials’ formulations are incompatible with
the instrument.
r Roche recommends that you carefully establish and monitor your participation in
external programs, and compare your results within your peer group using
cobas b 123 POC systems.
r Follow material instructions related to its transportation and storage conditions,
temperature equilibrium and mixing before use.
q
In cases where security level 3 or 4 is activated, the proficiency test function is available
only for the following operator profiles: trusted operator, service operator, key operator,
and supervisor.
