What type of testing does the DNR certify and register labs for?
The Wisconsin DNR certifies and registers laboratories for analytical chemistry and acute/chronic toxicity testing. Refer to the Program Information pages for more details. What is the difference between certification and registration? Laboratories can be either certified or registered through the laboratory certification program. In some cases, labs can also be recognized through reciprocity agreements with other states or certifying agencies. Certification is required for laboratories performing analytical testing commercially, either for regulated facilities or for special DNR projects. Registration is allowed for laboratories analyzing samples only for their own facility. Refer to the Program Information pages for more details.
