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.
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 2/5 (Moderate).
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.
