What Supports a “Sterile” Label on a Medical Device?
When someone opens a sterile medical device, they expect it to be ready for its intended use. Behind that expectation are several checks covering the sterilization process, the packaging and the product’s shelf life.
Here is a simple overview of what supports a “Sterile” label.
Working with an accredited testing laboratory
We work with an independent testing laboratory accredited by TAF to ISO/IEC 17025. Its accredited capabilities include sterility testing, measuring microorganisms on products, and checking that the test methods can reliably detect them.
These capabilities matter because products and materials can affect how microorganisms are recovered or detected during testing. A suitable test method helps provide reliable evidence for evaluating the sterilization process.
Validating sterilization and monitoring production
Sterilization validation uses tests and documented evidence to establish that a defined process can consistently achieve the required level of sterility.
During routine production, manufacturers follow established procedures for monitoring, testing and reviewing records. These activities help confirm that the process continues to operate within its validated conditions. The checks required depend on the product and the sterilization method.
Checking packaging over time
After sterilization, the packaging helps protect the device from contamination. Its ability to maintain that protection throughout the stated shelf life needs supporting evidence.
Aging studies evaluate the effects of time on the packaged product. After aging, checks such as seal strength and package integrity testing help assess whether the packaging can still maintain its protective barrier.
Accelerated aging can provide earlier evidence, supported by real-time aging studies to confirm performance over the stated storage period.
Confirming that the product still works
Storage can also affect the device itself. Manufacturers evaluate functions and properties that may change over time to confirm that the product continues to meet its performance requirements throughout its stated shelf life.
For users, these checks support a practical expectation. When the package is opened within its stated shelf life and under the specified storage conditions, the device should retain its sterility and perform as intended.
Understanding the testing behind the label helps make the quality of a sterile medical device easier to evaluate.
