Siemens ADVIA Centaur Calibrator A Kits Recalled for FT4 Bias
Siemens is recalling specific Calibrator A kits due to confirmed negative bias and potential calibration failures for the FT4 assay on certain ADVIA Centaur systems.
What this means for you
Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.
Our severity reasoning: The recall is classified as FDA Class II, but the source text does not report any hospitalizations, injuries, or illnesses. The hazard is a performance defect (negative bias/calibration failure) rather than a direct physical safety risk, fitting the Moderate category for low-risk contamination or performance issues without reported harm.
Plain-English summary
Siemens Healthcare Diagnostics is recalling 194 units of ADVIA Centaur Systems Calibrator A Kits. The affected lots are 08722A90, 27210A90, and 43429A90, all with an expiration date of July 24, 2017. These kits were distributed nationwide and to numerous international locations.
The recall was initiated because Siemens confirmed a negative bias for the Free T4 (FT4) assay when using these specific calibrator lots on the ADVIA Centaur, ADVIA Centaur XP, and ADVIA Centaur XPT Systems. Additionally, there is a potential for calibration failures due to above-limit calibrator RLU %CVs when using these lots with the FT4 assay. The performance of the FT4 assay on the ADVIA Centaur CP System is not affected by this issue.
Customers may continue to use the affected Calibrator A kit lots for the FT3, T3, T4, and TUp assays on the ADVIA Centaur Systems. The recall is limited to the FT4 assay on the specific system models mentioned.
