Sekisui Diagnostics Ammonia L3K Assay Recalled for Performance Issues
Sekisui Diagnostics is recalling specific lots of the Ammonia L3K Assay because atypical optical density decreases may impact performance at the high end of the linear range.
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: The recall is classified as FDA Class II, which typically indicates a situation where use of the product may cause temporary or medically reversible adverse health consequences. The specific hazard is a performance issue (atypical OD decrease) rather than a direct physical injury or contamination, fitting the Moderate category for a medical device with potential impact on test accuracy.
