Recall Insight
This FDA Devices action (record #Z-2445-2019) was formally reported on September 11, 2019, with the manufacturer initiating the action on July 2, 2019. It is classified under Moderate severity (Class II), with a current status of Terminated. Roche Diagnostics Operations, Inc. is listed as the recalling firm, operating out of Indianapolis, IN. Federal records indicate 4,309 (cobas c311-340 units;cobas c501-3,517 units;cobas c502 452 units units are affected, placing this recall in the million-unit bracket that typically triggers nationwide consumer alerts and retailer sweeps.
The documented reason for this recall is: The firm conducted internal investigations that confirmed customer complaints of quality control (QC) imprecision and calibration failures for the Tina-quant Myoglobin Gen.2 assay (catalog number 04580010190), lot numbe… Distribution data in the federal record shows the product reached: Nationwide. Distribution scope directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
To put this record in context, PlainRecalls indexes 83,949 recalls across the FDA, CPSC, NHTSA and USDA FSIS going back to 1995. Within the same product category, the database holds 6 closely related recalls, of which 6 were also issued by FDA Devices. That clustering is a signal — repeated actions in a narrow category often indicate a systemic quality-control issue, a supplier-wide contamination, or a design defect that has propagated across product lines. This recall is roughly 7 years old; older recalls can remain relevant because many units enter resale, rental, and secondary-market channels where the original warning never reaches the end user. Always cross-check the recall number against the official agency page before relying on any summary.

Product Description
The Tina-Quant Myoglobin Gen. 2 Tests system is an immuno-turbidimetric assay for the quantitative in vitro determination of myoglobin in human serum and plasma on Roche automated clinical chemistry analyzers
Reason for Recall
The firm conducted internal investigations that confirmed customer complaints of quality control (QC) imprecision and calibration failures for the Tina-quant Myoglobin Gen.2 assay (catalog number 04580010190), lot number 349860 on the cobas c311 analyzer and cobas c501 and c502 modules due to a drop in signal in the reaction kinetics. This signal drop was traced to an adjacent cell mixing effect. Sample recovery is decreased as a consequence of the disturbance in reaction kinetics. The investigation found discrepancies of up to -30%. Calibration, QC, and patient samples can be affected. The following issues were reported: - Calibration failures; Dup.E error due to signal drop in reaction kinetics - Sporadic quality control (QC) imprecision. As a long-term solution, the firm will implement required extra wash cycles (EWCs) into the respective Special Wash Requirements method sheets for the cobas c 311 analyzer and cobas c 501 and 502 modules, and into the cobas e-file for the cobas c 502 module. For the use of the reagent with the cobas c501 and c502, Roche will also direct users to run the Tina-Quant Myoglobin gen. 2 assay independently from other tests, in a batch mode status, with a maximum of 39 samples per run. Additionally, a change in the application settings of the Tina-quant Myoglobin Gen.2 assay on the cobas c 501 and 502 modules will be implemented so that adjacent cuvettes are no longer used in order to prevent adjacent cell mixing effects. The application settings change will be communicated at a later date.
