[52391803] The operator of an advia 2400 instrument reported a salicylate result of 29. 6 mg/l. When the sample was repeated; a negative value result was obtained. The customer recalibrated the method and reran patient samples previously reported, and results differed upon repeat testing. Corrected results were reported to the physician(s). There are no reports of patient intervention or adverse health consequences due to the discordant salicylate results.

[57588967] The initial mdr 2432235-2016-00488 was filed on august 17th, 2016. Additional information (08/31/2016): sample ids were provided for the results included in the initial report. A siemens headquarter support center (hsc) specialist evaluated the event data. Upon further investigation, the applications specialist found the customer is reporting in mg/l and not the standard mg/dl units. The standard units for salycilate per the instructions for use (ifu) are mg/dl. If the analytical measuring range (amr) of 3. 0 mg/dl - 100 mg/dl is translated to mg/l then the amr would be 30 mg/l - 1000 mg/l. The samples showing the imprecision were under 30 mg/l and thus are below the amr and siemens does not have precision or accuracy claims below the amr. The samples being tested are outside of the defined usage of this assay on the advia 2400 instrument. Reporting these samples would be considered non-standard usage by siemens. Instrument is performing according to specifications. No further evaluation of the device is required.
