Medical device safety alert: roche magna pure 96 instrument medical device manufacturer, roche diagnostics has issued a medical device safety alert concerning magna pure 96 instrument. the following devices are affected: material number 06541089001 (ivd labelled), serial number 4065 material number 05195322001 (lsr labelled), serial number 1115 there is a potential for sample mismatch when magna pure 96 xml order files are transmitted from any upstream instrument (including but not limited to hamilton magna starlet instrument) or any user developed“file sharing”order input to magna pure 96 instruments using magna pure software version 2.0.3 and earlier. with this current xml anomaly, the automated workflow is potentially impacted. the orders transferred from upstream instruments and/or an lis displayed in the magna pure 96 orders screen can be out of sequence, which can lead to mismatched sample information. the manufacturer explains that the magna pure 96 software assumes a one to one correlation between the “number” field specified in the xml file and the sample information and its actual sample position on the plate. automation partners who create xml file transmissions to be sent to the magna pure 96 instrument may not realize that the “number” field must be directly tied to the actual position in the plate, as this requirement is not explicitly stated in the magna pure host interface manual. if this is not followed, sample mismatches may occur when data is imported into the magna pure 96 software, without generating any error message or notification. if the xml interface functionality to downstream instruments is also utilized, then mismatched sample information would be passed on to the instruments where the samples are analyzed leading to results being assigned to the wrong samples. the magna pure 96 system host interface manual and software will be updated to address this issue. as an interim measure, customers using a magna starlet are advised to review the magna pure 96 orders tab and confirm that the correct sample order is associated with the appropriate corresponding plate well position before starting a run. customers using a lab developed system are advised to ensure that the orders are transmitted sequentially with no gaps. according to the local supplier, the affected products were distributed to hong kong. if you are in possession of the affected products, please contact your supplier for necessary actions. postedposted on 05 march 2014.
