  • 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.
