OPTI CCA-TS vs other Electrolyte Instruments on Whole Blood and Serum in a typical
setting
Excess blood aliquots from specimens collected for blood gas analyses were analyzed by both traditional
and non-traditional operators of measurement equipment in hospital laboratories. The sample was
analyzed on the OPTI CCA-TS after obtaining the requisite results from existing instrumentation used for
these analyses and operated and controlled following their established procedures.
