Medical Device Validation Testing for Sterility and Compliance

Sterilization and validation testing are essential to ensuring medical device safety, regulatory compliance, and successful commercialization. Life Science Outsourcing (LSO) provides end-to-end validation testing services to support medical device manufacturers from development through commercial production.

As an FDA-registered, ISO 13485–certified contract manufacturer, LSO supports compliance with ISO 11135, ISO 17665, ISO 11737, ISO 10993, and USP standards. Our integrated testing capabilities reduce risk, simplify validation, and accelerate timelines.

Bacterial Endotoxin Testing

Bacterial endotoxin testing (BET), or LAL testing, ensures that medical devices and materials meet pyrogen-free requirements to prevent harmful inflammatory responses in patients. LSO provides:

  • Limulus Amebocyte Lysate (LAL) testing for pyrogen detection
  • USP <85> and ISO 11737-1 compliant methodologies
  • Endotoxin detection for single-use and reusable medical devices

Bioburden testing measures the microbial contamination levels on a medical device before sterilization. Our services include:

  • ISO 11737-1 compliant bioburden testing
  • Quantification of aerobic, anaerobic, and fungal contaminants
  • Routine monitoring for process validation and control

Cytotoxicity testing evaluates the potential toxic effects of a medical device on living cells, ensuring biocompatibility and patient safety. LSO offers:

  • ISO 10993-5 compliant cytotoxicity testing
  • Elution, agar overlay, and direct contact assays
  • Comprehensive biocompatibility assessments

Regulatory-compliant labeling is critical for traceability, UDI compliance, and patient safety. LSO offers:

  • UDI-compliant labeling solutions
  • Tamper-evident and specialty labels
  • Full lot traceability and ERP-integrated tracking

Microbial identification is essential for understanding contaminant sources and mitigating risks in medical device manufacturing. Our testing includes:

  • Genotypic and phenotypic microbial identification
  • Bacterial, fungal, and yeast classification
  • Root cause analysis for contamination events

Sterility testing confirms that medical devices are free from viable microorganisms after sterilization. Our services include:

  • ISO 11737-2 compliant sterility testing
  • Direct immersion and membrane filtration methods
  • Testing for steam, EtO, gamma, and e-beam sterilized products
