Recall record

Recall number: Z-1421-2020
Classification: Class II
Status: Open, Classified
Initiated: 2020-01-12
Posted: 2020-03-02
Recalling firm: Siemens Healthcare Diagnostics Inc.
Product: Atellica CH Reaction Ring Segment, SMN 11099326, UDI 00630414596143
Product code: JGS Electrode, Ion Specific, Sodium
Reason for recall: Some lots ending in "17", "18", "19", or higher may have cuvette defects allowing water from the water bath to contaminate the interior of the cuvette, which may falsely elevate or depress sample results.
FDA root cause: Under Investigation by firm
Action: The firm distributed Urgent Medical Device Correction letters to all affected customers on January 17, 2020. Customers were asked to check each Atellica CH 930 Analyzer in their laboratory as well as in their inventory for impacted cuvette lot numbers ending in "17" or "18" (6th and 7th digits). These devices must be purged from the customer's inventory. If the customer does not have enough cuvette segments of the unimpacted lot in their inventory, they may contact customer service. Detailed instructions were provided in the appendices to the customer letter. ***Updated 3/2/2020*** An updated Urgent Medical Device Correction was distributed to all customers on February 26, 2020, due to the recalling firm adding cuvette segment kit lots ending in "19" to the affected products list. The follow-up communication advises customers of the potential for falsely depressed or elevated results from Atellica CH reaction cuvette segments with the kit lot ending in "19" and above, due to a cuvette defect allowing water bath to contaminate the cuvette. Customers who routinely run the CO2_c assay will be instructed to run 300 replicates of the CO2_c calibrator on their analyzer in order to cover all cuvette positions. The customers will then follow the instructions provided in the communication and will use the mean value of the 300 replicates to determine if there is cuvette impact. If all individual calibrator results are d12% of the mean calibrator value, no further action is required, and the laboratories can continue to process patient samples. If any individual calibrator result is >12% of the mean calibrator value, customers will be asked to contact Siemens Customer Care Center to determine additional action to be taken prior to processing patient samples. Customers who do not routinely run CO2_c samples in their laboratory will be instructed to run all patient samples in duplicate for every assay except Sodium, Potassium, and Chloride. Customers will be asked t

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.
