SMPR CHALLENGES - PRECISION

• Method precision depends on sample homogeneity, particle size, test portion size, and extraction solvents/conditions. • Pre-extraction preparation of samples (grinding/homogenizing) will be critical for managing variation. • Test portion sizes may be larger than usual • RSD criteria may be dependent on mean • RSD Criteria for oats may be larger than usual, even for ELISA methods
