Kaluza C Flow Cytometry Software Recalled for Potential Erroneous Results

The FDA is recalling Kaluza C Flow Cytometry Software versions 1.0, 1.1.1, and 1.1.2 due to software anomalies that may generate erroneous results affecting diagnostic interpretation.

What this means for you

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: FDA Class II precautionary recall with no reported illnesses or injuries. The hazard—software anomalies that may generate erroneous results—is theoretical and affects diagnostic accuracy rather than direct patient safety, consistent with a precautionary quality recall.

Plain-English summary
