Interferences
The OPTI CCA Ca
++
sensor does exhibit an interference from bisulfate and phenylacetic acid.
Heparin salts are the only acceptable anticoagulants. Other anticoagulants such as citrate, EDTA, oxalate,
and uoride cause signicant interferences to the electrolyte sensors.
The following exogenous interferents were quantied in tonometered plasma, 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 platform, with a standard OPTI style Ionized Calcium 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.
Substance Amount Ca
++
change (mmol/L)
Sodium uorescein 26 mg/dL unstable
Cardio (indocyanine) green 0.5 mg/dL +0.1
Methylene blue 25 mg/dL unstable
Only clear, uncolored quality control materials, such as OPTI CHECK or OPTI CHECK PLUS brand
aqueous controls should be used with the OPTI CCA-TS2 system. Colored materials, including
prociency testing materials, may interfere with the ionized calcium measurement, or fail to be properly
aspirated.
