Siemens N Protein Standard SL Recalled for Inaccurate Ceruloplasmin Calibration
CSL Behring GmbH is recalling Siemens N Protein Standard SL and N/T Protein Controls SL due to incorrect value assignments that cause negative bias in Ceruloplasmin test results.
The agency’s classification
FDA (Devices): Class II
Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.
This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work
What this means for you
Our assessment, not the agency’s: severity 2/5 (Moderate).
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 hazard involves inaccurate test results (negative bias) rather than direct physical injury or contamination, fitting the criteria for moderate severity involving potential diagnostic errors without reported harm.
Plain-English summary
CSL Behring GmbH is recalling specific lots of SIEMENS N Protein Standard SL and N/T Protein Controls SL (Levels Low, Mid, and High) used for Ceruloplasmin testing on BN II and BN ProSpec Systems. The recall is due to incorrect value assignments in the standards and controls, which resulted in a negative bias of approximately -20% for Ceruloplasmin results. This means the test results were lower than they should have been when using the affected lots.
The affected products were distributed worldwide, including in the United States, Canada, and numerous countries across Europe, Asia, and the Americas. The recall covers specific lot numbers with expiration dates ranging from July 2017 to July 2018. Siemens Healthcare Diagnostics confirmed that the N Antiserum to Human Ceruloplasmin (REF OUIE) works as intended and is not affected by this issue.
Healthcare facilities and laboratories should stop using the affected lots of N Protein Standard SL and N/T Protein Controls SL for Ceruloplasmin calibration. Users should contact CSL Behring GmbH or Siemens Healthcare Diagnostics for instructions on how to return the affected products and obtain replacements.
