OPTI CCA-TS vs other pH Instruments on whole blood in a typical setting
Excess blood aliquots from specimens collected for blood gas analyses were analyzed by both traditional
and non-traditional operators of blood gas equipment in hospital laboratories. The blood 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.
