HemosIL Liquid Anti-Xa Assay On-Board Stability Issue Recall

Instrumentation Laboratory is recalling HemosIL Liquid Anti-Xa, a coagulation assay measuring heparin activity, due to reduced on-board instrument stability from 7 days to 5 days.

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 without reported illnesses or injuries. The issue involves reduced on-board instrument stability for a laboratory device, representing a device performance change rather than an explicitly identified patient safety hazard. This falls under the category of voluntary precautionary recalls.

The device runs on IL Coagulation Systems including ACLTOP Family, ACL TOP Family 50 Series, and ACL Elite/Elite Pro analyzers. Approximately 40,224 units have been distributed in the United States and internationally.
