Ethylene Oxide (EO) Residuals Testing

Medical devices sterilised with Ethylene Oxide gas must be tested to ensure any residual sterilant or degradation byproducts are below limits that may pose a toxicological risk to the end users. Many factors can impact the levels of Ethylene Oxide Residuals following sterilisation, such as packaging type, material of components, sterilisation cycle parameters, and load density, thus it can be difficult to predict when a product would be safe for release to the public. Consequently, regulatory bodies require that testing is performed and the quantities of these residuals confirmed before a medical device is released. Failing to provide proof of the completion of such testing can delay the launch of your medical device and create supply chain issues for the manufacturer.

Eurofins Medical Device Testing’s network of laboratories offers Ethylene Oxide Residuals Testing to provide clients with one source for all necessary residual and sterility tests on a medical device. Our team has extensive experience in testing for Ethylene Oxide Residuals and working with clients to navigate the ISO 10993-7 testing requirements. Your company will have direct communication with our laboratory to guarantee your medical device is tested to the appropriate standards.
