Some LER masks pyrogenic endotoxins. Requires case-by-case risk assessment. | | "Just use rFC instead of LAL to fix LER." | Both LAL and rFC suffer equally from LER because the mechanism is biochemical masking, not reagent specificity. | | "The FDA rejects products with LER." | Incorrect. The FDA accepts products with LER if properly documented and justified using TR 82 principles. |
The answer to standardizing investigation and mitigation of LER came in 2011 from the Parenteral Drug Association (PDA). Their solution was , titled "Low Endotoxin Recovery." For quality control (QC) microbiologists, analytical chemists, and regulatory affairs professionals, accessing the PDA Technical Report 82 PDF is not a luxury—it is an operational necessity. pda technical report 82 pdf
