SODIUM ANALYTES
Direct linearity for the OPTI CCA-TS2 measurement has been established against reference materials or
methods. The linearity of the Sodium sensor on the OPTI CCA-TS2 has been established versus the same
sensor on the OPTI CCA-TS using whole blood samples tonometered with mid level mixtures and spiked
or diluted to establish the correlation.
