Interferences
The following exogenous interferents were quantified in tonometered whole blood samples spiked with a
number of endogenous and exogenous chemicals and tested for interference following the CLSI guideline
EP7-A2, showing interferences to dyes which typically have short half-lives within the body before being
metabolized by the liver. This testing was done on the OPTI CCA-TS platform, with a standard OPTI
style Lactate sensor. No changes were made to the sensor or the measurement principle, so the
interference of the OPTI CCA-TS2 is equivalent to the OPTI CCA-TS.
