Siemens Recalls Dade Actin FSL Activated PTT Reagent Due to Heparin Sensitivity
Siemens Healthcare Diagnostics is recalling specific lots of Dade Actin FSL Activated PTT Reagent because they show increased heparin sensitivity over their shelf life.
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: The recall is classified as FDA Class II, and the source text describes a performance deviation (increased heparin sensitivity) without reporting any illnesses, injuries, or deaths. This aligns with the rubric for moderate severity involving low-risk contamination or performance issues without reported harm.
