PDA Technical Report No. 82 (TR 82) provides comprehensive guidance on Low Endotoxin Recovery (LER), a phenomenon where endotoxins in biopharmaceutical formulations become masked and undetected by standard LAL assays. The 128-page report covers scientific mechanisms, hold-time study design, and mitigation strategies, including 12 case studies on root causes and demasking. The report defines LER as failing to recover more than 50% of spiked endotoxin activity over time. Purchase the official report at the PDA Bookstore .
