Introduction on CRO for E&L Testing of Medical Devices
Selecting the right CRO for E&L testing in medical devices: what to look for goes far beyond checking off a regulatory requirement—it’s a strategic decision that plays a direct role in protecting patient health, meeting ISO 10993-18 standards, and ensuring the successful launch of your product. The quality and accuracy of Extractables and Leachables (E&L) testing can influence everything from approval timelines to long-term market performance.
At ResolveMass Laboratories Inc., we recognize the importance of this process and bring decades of focused expertise to every project. Our team is committed to delivering precise, regulatory-compliant E&L data tailored to your device’s materials and risk profile.
In this article, we’ll explore the key factors to consider when choosing the right CRO for E&L testing in medical devices: what to look for in a partner who can support both your compliance needs and innovation goals effectively.
What Is E&L Testing in Medical Devices?
E&L (Extractables and Leachables) testing identifies chemicals that can migrate from medical device materials into patients or drugs. This testing helps evaluate:
- Material biocompatibility
- Potential health risks
- Regulatory readiness for FDA, ISO, and USP submissions
By understanding what chemicals may leach out of your product, you can reduce safety risks and avoid delays in product approval. A capable CRO will analyze both extractables under forced conditions and leachables under real-use scenarios to ensure full risk coverage.

Why Choosing the Right CRO for E&L Testing in Medical Devices: What to Look For Is Important
Not all CROs offer the same level of expertise or flexibility. A skilled CRO provides:
- Accurate chemical identification with advanced tools
- Detailed toxicological reviews and safety insights
- Fast, traceable reporting aligned with global regulations
Working with the right partner reduces the risk of test failures, costly delays, or incomplete data submissions. Your CRO should adapt to project changes, offer support during audits, and act as a true extension of your development team.

Key Factors to Consider: Choosing the Right CRO for E&L Testing in Medical Devices
1. Proven Experience in Medical Device Chemistry
Choose a CRO with deep knowledge in medical device materials—not just pharmaceutical packaging. Look for case studies or examples of work with tubing, polymers, connectors, and combination products. A CRO familiar with your materials will avoid common mistakes and streamline testing.

2. Access to Advanced Analytical Instruments
Your CRO should have in-house tools like GC-MS, LC-MS/MS, ICP-MS, FTIR, and NMR. These instruments allow precise detection of both organic and inorganic compounds at low levels. Comprehensive testing ensures no harmful substances are missed during screening.
3. Strong Regulatory Knowledge (FDA, ISO, USP)
The CRO must understand standards like ISO 10993-18, USP <1663>/<1664>, and FDA guidance. This ensures your data meets submission requirements the first time. Their team should stay updated on evolving regulations and know how to structure data for easy review.

4. Customized Testing Based on Your Product
No two devices are the same. The best CROs offer tailored test protocols based on your materials, use conditions, and risk level. Flexible study design reduces over-testing and cuts unnecessary costs while meeting all compliance needs.

5. Transparent Data and Audit-Ready Reports
Look for a lab that provides raw data, detailed SOPs, and clear documentation. Everything should be traceable and ready for audits. Reliable reporting not only builds trust with regulators but also helps your internal teams make informed decisions.
6. Timely Results and Adaptable Project Plans
Time is critical in product development. A good CRO should adjust to changing deadlines, allow for protocol updates, and avoid bottlenecks. Agile labs will work with your timelines, not against them.
7. Clear and Honest Pricing
Avoid hidden charges or vague quotes. A trustworthy CRO offers a transparent cost structure that breaks down each service—sample prep, analysis, toxicology, and reporting. This helps with budgeting and shows they value partnership.

FAQs: Choosing the Right CRO for E&L Testing in Medical Devices
A CRO (Contract Research Organization) performs extractables and leachables testing to identify any chemicals that may migrate from a medical device into the body or associated drug product. This includes designing the test strategy, performing chemical analysis, and interpreting the results for regulatory submissions. A reliable CRO ensures the testing process is accurate, compliant, and aligned with international guidelines.
E&L testing is essential because it helps detect potentially harmful substances that could leach from the device during use. These chemicals can pose serious health risks if not identified early. By conducting thorough E&L testing, manufacturers ensure device safety and meet the regulatory expectations set by bodies like the FDA and ISO.
To choose the right CRO, look at their experience with medical device testing, access to advanced instruments, understanding of regulations, and ability to customize protocols. Also consider their communication, turnaround time, and how transparent they are with costs and data. A good CRO should act as a partner, not just a service provider.
Key standards include ISO 10993‑18 for chemical characterization and ISO 10993‑17 for toxicological risk assessment. In addition, USP <1663> and <1664> offer guidance for extractables and leachables studies. Your CRO should follow these standards closely to ensure your results are acceptable for global regulatory bodies.
