The National Plant Diagnostic Network strives to enhance agricultural security through the protection of the health and productivity of plants, in the agricultural and natural ecosystems, in the United States.
NPDN established a Core standard to provide an overarching framework for all NPDN member laboratories to commit to excellence 
in plant diagnostics by achieving core accreditation. Accreditation ensures NPDN laboratories will meet quality standards, enhance professionalism, strengthening our state of readiness in performing timely accurate detections while reducing the risk of exotic pathogens and pest establishments.
