4 principles

The methods and equipment used to determine seed health should meet the requirements for health determination purposes. Assay methods should have different sensitivities

And reproducibility. In the case of health determination, the method of detection is selected based on the detected pests, the type of seeds and the purpose of the assay. Detection method should be done

It is possible to accurately detect the pathogen and pest designated by the submitter for detection.
