BUN/UREA ANALYTES
Direct linearity for the OPTI CCA-TS2 measurement has been established against reference materials or
methods. The linearity of the BUN (urea) 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.
