Manufacturer Narrative

Product labeling states: "intended use: immunoassay for the in vitro quantitative determination of human insulin in human serum and plasma." product labeling also states: "samples from patients treated with bovine, porcine or human insulin sometimes contain anti-insulin antibodies.15,9 insulin bound to these antibodies is at least partially recognized by the antibodies used in the elecsys insulin assay.16".As the intended use of the elecsys insulin assay is the determination of human insulin, this may possibly explain the high result when the patient was given actrapid.Actrapid is human insulin.Furthermore, the patient has insulin antibodies.Insulin bound to anti-insulin antibodies are known to be at least partially recognized by the elecsys insulin assay.No sample from the patient was available for further investigation.The investigation could not identify a product problem.The cause of the event could not be determined.
