Abstract：For 3 kinds of maize matrix reference materials with different genetically modified MON810 maize contents, a multi-laboratory verification for their Q-PCR values is organized. The uncertainties of the multi-laboratory values are evaluated. By weighted average, the Q-PCR values and uncertainties of A, B and C levels of the genetically modified MON810 maize matrix reference materials are 0.51%±0.10%, 1.1%±0.2%, 4.7%±0.7% (k=2), respectively.
