Techno-Path Multichem AE Quality Control Material Recalled for Stability Drift

Techno-Path is recalling Multichem AE Unassayed Level 3 quality control material because stability drift affects the Ammonia analyte, potentially delaying diagnostic results.

The agency’s classification

FDA (Devices): Class II

Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.

This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work

What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall is classified as Class II, and the source states that delayed diagnosis of elevated Ammonia levels may impact the 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 Techno-Path Multichem AE Unassayed Level 3, REF:AE623X. The recall is limited to Lot # 65705263, which was distributed nationwide in the state of Massachusetts.

Routine stability studies identified a stability drift affecting the Ammonia (NH4+) analyte in specific lots of the Multichem AE quality control material. 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 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.
