Recall record

Recall number: Z-2049-2017
Classification: Class II
Status: Terminated
Initiated: 2017-03-21
Posted: 2017-05-09
Terminated: 2017-10-02
Recalling firm: Roche Diagnostics GmbH
Product: Sample probes associated with: cobas 6000 Series System, cobas 8000 Modular Analyzer Series, cobas c 311 analyzer cobas c 501/502 cobas c 701/702 cobas 8000 ISE Product Usage: The cobas 6000 series is a fully automated, random-access, software-controlled system for immunoassay and photometric analysis intended for qualitative and quantitative in vitro determinations using a wide variety of tests. It is optimized for high throughput workloads in the professional environment using a combination of Ion selective electrodes (ISE), a photometric analysis unit an immunoassay analysis module. The cobas 8000 Modular Analyzer Series is a fully automated system for Clinical chemistry analysis, intended for the in vitro qualitative and quantitative determination of analytes in body fluids. It is optimized for high throughput workloads in the professional environment using a combination of ion selective electrodes (ISE) and a photometric analysis unit. The cobas c 311 analyzer is an in-vitro diagnostic analyzer capable of performing clinical chemistry, specific protein and electrolyte tests. Analytes are measured photometrically or turbidimetrically; the analyzer also has an optional ISE module for measuring sodium, potassium and chloride.
Product code: JJE Analyzer, Chemistry (Photometric, Discrete), For Clinical Use
Reason for recall: Due to a design change in 2015, corrosion on the sample probe electrical contacts can occur and lead to a disturbance of the sample liquid level detection (LLD). When disturbance of the sample liquid level detection (LLD) occurs, the affected sample probe may dip into the sample material deeper than intended. This may lead to carryover and medical risk cannot be excluded.
Root cause tag: design
FDA root cause: Component change control

About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
