Hazard Information

Software defect, which allows the system to accept erroneous, non-monotonous calibrations for Spline-type assays. Cobas pro integrated solutions is an automated analyzer, intended for running qualitative, semi-quantitative and quantitative clinical chemistry and immunochemistry assays, as well as ion-selective measurements. When an erroneous calibration is active, the instrument fails to calculate new values and instead repeats the last successfully calculated result from any Spline-type assay for all subsequent measurements, leading to identical and erroneous patient and QC results. The defect could lead to patients receiving erroneous lab results, which could result in a remote risk of serious adverse health consequences. The following assays use spline type calibration and are affected by this issue: Cystatin C Gen.2, Ferritin Gen.4, Lipoprotein (a) Gen. 2, Lipoprotein (a) molarity, Vancomycin Gen.3, Kappa Free Light Chains Partner Channel, Lambda Free Light Chains Partner Channel, and fCAL turbo Partner Channel.

What You Should Do

Industry Context

This recall is not stated as part of a broader industry pattern.

Real-World Impact

Labs may produce inaccurate results. This can affect diagnosis and treatment plans and may require retesting and clinical review.
