PRECISION CHALLENGES
7
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
