Cobas b 123 POC system The cobas b 123 POC system is a fully automated POC system for whole blood in vitro measurement of pH, blood gases (B3G), electrolytes Nat, K+, iCaWt (ISE), hematocrit (THct), metabolites (Glu, Lac), total hemoglobin (tHb), hemoglobin derivatives (O2Hb, HHb, COT~b, MetHb), and oxygen saturation (SO2). In addition, the cobas b 123 POC system calculates derived parameters. It is dedicated for use in a Point-of-Care environment and laboratory. The integrated AutoQC module and the oximeter module are available as an option

under specific settings, an issue may occur during simultaneous Sensor Cartridge and Fluid Pack change on the cobas b 123 <2> POC system and cobas b 123 <4> POC system. The issue occurs when the software function [AutoQC as follow-up] is configured to run all three levels of AutoQC only after a Fluid Pack change, but not after a Sensor Cartridge change. When both are changed simultaneously, starting with the Sensor Cartridge and followed by the Fluid Pack, the analyzer carries out only the follow-up actions associated with the Sensor Cartridge change after completing the change workflow. As a result, no follow-up AutoQC is performed and the three expected AutoQC measurements for the Fluid Pack change are not carried out. Without running quality control, there is a remote possibility that system issues would not be detected and wrong results would not be excluded on all parameters: pH, PO2, PCO2, Na+, K+, Ca++, Cl-, Glu, Lac, Hct, SO2, O2Hb, COHb, MetHb, HHb, and Bili.
