Our assessment, not the agency’s: severity 3/5 (High).

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: The recall involves a quality control material with a stability drift in the Ammonia analyte that may delay diagnostic results and impact timely treatment of life-threatening levels. The source does not report any illnesses, injuries, or deaths.

Plain-English summary

Techno-Path Manufacturing Ltd. is recalling 832 units of Multichem AE Unassayed Level 1 quality control material (REF:AE621X). The recall is due to a stability drift identified in routine stability studies that affects the Ammonia (NH4+) analyte in specific lots. Additional testing confirmed that the labelled shelf-life performance claim for the Ammonia analyte can no longer be supported for the affected lots. This issue is limited to the Ammonia analyte only.

The affected product was distributed nationwide in the United States, specifically within the state of Massachusetts. The impacted device may cause a delay in issuing results to the physician. Delayed recognition and diagnosis of elevated levels may impact the timely treatment of life-threatening levels described within medical toxicity intervention decision points.

The source does not report any illnesses, injuries, or deaths associated with this recall. Users should stop using the affected lots and contact the manufacturer for further instructions.
