One Step K in vitro diagnostic test recall for missing FDA clearance

DFI Co., Ltd. is recalling One Step K in vitro diagnostic test devices (761 units) because they were distributed without required FDA premarket clearance or approval.

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: This is an FDA Class II recall. The source text states no reported illnesses or injuries, and the hazard is regulatory non-compliance (missing premarket clearance) rather than a direct safety or performance defect. Class II recalls without reported adverse events typically fall in the Moderate range per the rubric.
