Ortho VITROS URIC Slides Recalled Due to NAC Interference

Ortho-Clinical Diagnostics is recalling VITROS URIC Slides because N-Acetylcysteine (NAC) can interfere with the assay results.

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, but the hazard is an analytical interference (NAC) rather than a direct physical injury or high-risk pathogen, fitting the criteria for moderate severity involving potential diagnostic errors without reported harm.

Plain-English summary

Ortho-Clinical Diagnostics is recalling VITROS Chemistry Products URIC Slides (REF/Product Code 194 3927) because the company confirmed that N-Acetylcysteine (NAC) can interfere with the assay. NAC is a drug used for acetaminophen overdose, mucolytic therapy, and as a nutritional supplement.

The recall affects sales units distributed worldwide, including the United States, Puerto Rico, Bermuda, and various international markets. The affected product lots are identified by Generation numbers 26, 27, 28, 29, and 31.
