Reason

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.
