Interferences

The following exogenous interferents were quantied 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 pH 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
