ANALYTES POTASSIUM
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.

Linearity
Wherever possible, linearity for the OPTI CCA measurement has been established against reference
materials or methods. Potassium linearity is established by measurement of gravimetrically prepared,
N.I.S.T. traceable aqueous standard solutions (Potassium
ST
) and by measurement of N.I.S.T. Standard
Reference Material 956a Electrolytes in Human Serum (Potassium
NIST
). No changes were made to the
Potassium sensor or the measurement principle, so the traceability of the OPTI CCA-TS2 is equivalent to
the OPTI CCA.
