Most Asked FAQs on E&L Testing
Extractables are chemicals that can be forced out of materials under extreme laboratory conditions such as heat, solvents, or stress. Leachables, on the other hand, are compounds that migrate into a product during normal use or storage. Both need to be identified because they may pose safety risks to patients.
E&L testing is a regulatory requirement to ensure that harmful compounds are not transferred from packaging or devices into the final drug or product. The FDA and USP mandate it to confirm patient safety, product quality, and compliance with global safety standards.
The best CRO combines proven experience, advanced analytical technology, and in-depth knowledge of regulatory standards. It should also offer custom study designs and reliable timelines. Together, these factors help clients achieve faster approvals and safer product launches.
The Analytical Evaluation Threshold, or AET, is a safety-based value used to decide which compounds detected during testing must be reported. It ensures that only relevant chemicals are included in the safety assessment, making studies accurate and regulatory-ready.
Yes, any device that comes into direct contact with patients, their fluids, or drug products must undergo E&L testing. This evaluation ensures the device materials do not release toxic compounds, safeguarding both patient safety and regulatory compliance.
A controlled extractables study involves exposing materials to exaggerated conditions such as extreme temperatures, solvents, or pressure. These stress conditions force potential extractables to appear, helping scientists build a comprehensive chemical profile for safety analysis.
