Section NR 149.04 - Disclaimers

A laboratory may not claim or imply that data it generates has department approval solely on the basis of the laboratory's certification and registration status.

Certification or registration of a laboratory is not an endorsement by the department of the quality or validity of the data generated by a laboratory. Certification or registration does not guarantee the usability of data generated by a laboratory for an intended purpose. The covered programs under this chapter are the ultimate users of laboratory results and determine whether they accept or reject analytical data from any certified or registered laboratory.
