Should a laboratory test for analytes beyond the analytes required in chapter 314-55 or 246-70 WAC, they must adhere to the following guidelines:

(1) Additional test results must be identified as analytes outside the scope of accreditation on the certificate of analysis.

(2) Additional analytes that are tested using methods that also include required analytes for compliance must meet similar requirements for testing and reporting.

(3) Additional analytes that are tested using methods that do not include required analytes for compliance must be validated and tested using standards established in this chapter.
