Foods containing more than 0.9% GMO by weight must be so labelled; providing the consumer the opportunity to make an informed(?) choice. The commercial costs of erroneous labelling could be considerable. The costs of false test results, or false interpretations of test results could also be considerable. The article shows good reason to doubt the usefulness of current quantification techniques; do they actually meet the needs of regulation?

“European GMO labeling thresholds impractical and unscientific”
The report provides guidance on measurement tolerances. Insurers may wish to avoid allowing labs to quote unrealistic precision; error has a high commercial value.
