Clinical Chemistry Analyzer Software Flaw May Cause Inaccurate Test Results

Siemens is recalling Atellica CH 930 clinical chemistry analyzers with software v1.25.1 or lower. Two software defects could cause inaccurate test results: test parameters may revert to defaults, or the analyzer may use expired reagents.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is a Class II medical device recall involving a risk-of-harm product (clinical chemistry analyzer capable of producing diagnostic errors). No illnesses, injuries, or hospitalizations are reported in the source text, and the hazards remain theoretical. This meets the criterion for a High severity rating per the rubric.

Plain-English summary

Siemens Healthcare Diagnostics is recalling approximately 2,980 units of the Atellica CH 930 clinical chemistry analyzer with software version V1.25.1 or lower. The analyzer has been distributed nationwide and internationally across numerous countries.

The recall was initiated due to two software defects. Test Definition parameters for Open Channel Assays may revert to default values rather than maintaining user-configured settings, which can shift test results by the magnitude of the configured Assay Correlation factor. Additionally, the On Board Stability feature may fail to update when manually changed, allowing the analyzer to continue using expired reagents when testing Open Channel Assays.

These defects present a risk that the analyzer may produce erroneous results when analyzing patient samples. Healthcare facilities and laboratories that use affected analyzers should contact Siemens Healthcare Diagnostics for corrected software versions or additional guidance.
