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
Check against the official notice below — it lists the full affected range.
Roche Diagnostics Operations, Inc. is recalling 30 cobas b 123 POC systems (models <2> and <4>) used to measure blood gases, electrolytes, and other parameters from whole blood samples. Under specific software settings, a problem can occur when a Sensor Cartridge and Fluid Pack are changed at the same time. When this happens, the system may skip quality control testing that should follow the Fluid Pack change, meaning it would not detect system problems or exclude incorrect test results for 16 different measured parameters including pH, blood gases, electrolytes, and other blood chemistry values.
The recall affects 30 devices distributed nationwide across California, Louisiana, Nebraska, Puerto Rico, South Carolina, Texas, Virginia, and West Virginia. The source document does not specify what action affected consumers should take in response to this recall.

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.
