Regulations require that diagnostic microbiology laboratories verify or validate the performance characteristics of tests prior to reporting patient results. Regulations and guidance documents provide information to help laboratories navigate this process, but this still remains one of the least clear responsibilities of the laboratory. Questions such as “Do I validate or verify?” “Does this change require validation?”, and “How do I verify this new test?” are common. This workshop will focus on the regulatory requirements for the verification and validation of tests performed in the diagnostic microbiology laboratory. The differences between verification and validation will be reviewed. A number of validation/verification cases will be presented and discussed.


After attendance, participants will be able to:

1. Define verification and validation.

2. Describe components of the verification and validation processes.

3. Recognize the verification requirements for unmodified FDA-cleared tests.

4. Identify the verification requirements for modified (off-label) commercial tests and laboratory-developed tests.
