MAUDE data represents reports of adverse events involving medical devices. This maude entry was filed from a 01,05,06 report with the FDA on 2013-12-20 for DIMENSION(R) CLINICAL CHEMISTRY SYSTEM DF89A manufactured by Siemens Healthcare Diagnostics Inc - Glasgow.
[4128077]
Customer reported variability of recovery of qc samples for cyclosporin a (csa) depending upon length of time running the samples within the reagent open well claim. The customer reported qc out of range results occured unless the flex reagent wells had been pre-hydrated 2-3 hours prior to running the control. It is unknown if patient treatment was altered or prescribed due to the variable results with time after hydration of the csa reagent open wells. There was no report of adverse health consequences as a result the variability of results.

The cause of the qc variability and low level qc out of range recovery is likely related to poor open well stability of the csa reagent. A chrome particle reagent used in common with the dimension vista csa reagent, (b)(4), is the likely cause. Siemens healthcare diagnostics has confirmed complaints regarding variability of recovery of qc and patient results with the (b)(4) flex reagent cartridge lots 12300bb, 12318bb, and 13011bb. Internal testing has confirmed atypical performance and increases of >25% over several days for samples with csa concentrations below 125 ng/ml. Daily qc can detect performance variations in the assay. Errors are most pronounced below 125 ng/ml where maintenance therapy occurs, therefore dosage adjustment based on a single result is extremely unlikely. Nevertheless, siemens issued an urgent medical device recall communication 13-90 to customers who had ordered these lots advising them to discontinue use and to discard the dimension vista lots.
