OPTI CCA vs other pH/Blood Gas 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 after obtaining the requisite results from existing instrumentation used for these analyses
and operated and controlled following their established procedures.
