Recovery and Precision in Human Whole Blood

To prepare samples for analysis, blood was collected in heparinized vacuum tubes
and tonometered at 37
-
Cl , and Ca
levels to prepare samples for pCO
performed using these samples on a minimum of 3 Rapidlab 1260 systems
The following tables summarize the results of the Rapidlab 1260 system human
