OPTI CCA-TS vs other Lactate Instruments on whole blood in a typical setting
Excess sample aliquots from specimens collected for metabolyte 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.
