Medical Device Sterilization Services

At Cretex Medical | QTS we offer a full suite of medical device sterilization management services designed to help you achieve sterility assurance, regulatory compliance, and speed to market. Our certified microbiologists and engineers provide hands-on guidance throughout the process, from protocol development to third-party lab coordination, so you can focus on what you do best: delivering life-changing medical technologies.

Sterilization isn’t one-size-fits-all. We can partner with you to execute your sterilization plan or work with you to determine the most effective and efficient method based on your device design, materials, and regulatory requirements.

Sterilization Methods:

• Ethylene Oxide (EO / EtO)
• Gamma Irradiation
• Electron Beam (E-Beam)
• X-ray
• Moist Heat (Steam)
• Custom methods based on unique product needs

Whether you’re starting a new validation or transferring an existing process, we provide seamless coordination from start to finish.

Our sterilization experts oversee every step of the validation process, helping you meet strict industry standards while reducing time, cost, and risk. We also manage production-cycle coordination and third-party testing partnerships, giving you a single point of contact and total project visibility.

Sterilization Validations:

• EO sterilization validations
• Gamma/E-beam/x-ray dose setting & audits
• Annual EO requalification assessments and periodic requalification studies

Laboratory Testing Management:

We partner with a variety of labs to offer the microbiological and chemical tests needed to validate and ensure ongoing compliance of your sterilization process.

• Bioburden testing
• Microbial identification
• Product & BI sterility testing
• Endotoxin testing
• EO residuals testing

Sterilization compliance requires consistency. Our team actively monitors important milestones such as periodic requalifications and dose audits, notifying you in advance to keep your project on track and regulatory-ready.

We help you avoid delays and non-conformances through:

• Proactive process management
• Meticulous documentation
• Timely alerts for testing and audit requirements
• Bioburden data trending

Looking to reduce the cost of validations? Our microbiologists and engineers can help establish product families, allowing a single representative device to stand in for multiple SKUs during validation. We support:

• EO and radiation sterilization family groupings
• Justification of family logic
• Selection of representative products

This strategic approach allows you to minimize testing while staying fully compliant with global sterilization standards.
