Manufacturer Narrative

Initial mdr 2517506-2021-000130 was filed on 28-may-2021.Additional information (04-june-2021): siemens healthcare diagnostics headquarters support center (hsc) concluded their investigation of the microalbumin proficiency survey failure on a dimension® exl¿ 200 system.Hsc reviewed the information provided by the customer and the instrument data files.Hsc evaluation showed that the assay range for the microalbumin (malb) assay was set incorrectly on the system as 1.3-850 mg/l rather than 1.3-100 mg/l which is the assay range listed in the malb instructions for use (ifu).Once this setting was corrected, the survey sample result recovered acceptably.Microalbumin (malb) quality control (qc) recovery was in range.The customer was processing the malb survey samples in a non-standard malb configuration, outside the assay range indicated in the instructions for use for the malb assay causing the survey failures.The customer reset the malb assay range to the ifu defined assay range and continues to process acceptably with no issues reported.A potential product issue was not identified.The instrument is fully operational.The device is performing within specifications.No further evaluation is required.Section h6 has been updated to reflect the hsc investigation.
