The cause for the discordant advia centaur xp cyclosporine (csa) results is unknown.Siemens reviewed the customer data.The overall bias is in line with what is expected in the advia centaur cyclosporine ifu (instructions for use), 10629836_en rev, k, 2017-12 accuracy/method comparison section with tandem-ms.In addition the advia centaur cyclosporine assay does not have a claim to be comparable to any other methods or platforms.The lc/ms/ms methods also do not seem to be in alignment with each other and demonstrate variability.The instrument is performing within specifications.No further evaluation of the device is required.The ifu states in the interpretation of results: "results of this assay should always be interpreted in conjunction with patient's medical history, clinical presentation and other findings." the ifu states in the limitations section: "always use measurements of csa in conjunction with other diagnostic procedures, including information from the patient's clinical evaluation.".
