Topic 4 :: Interpreting Mixtures
Mixture Laboratory Reporting
Laboratories may vary in the way in which they report mixtures:
- Report the presence of a mixed sample, without an accompanying statistical weight calculation
- Report the presence of a mixed sample and calculate a random match probability (e.g., when a major contributor can be clearly interpreted)
- Report the presence of a mixture and calculate the combined probability of inclusion (such as a random match probability) or a combined probability of exclusion
- Report the presence of a mixed sample and calculate the likelihood ratio of the known contributors to the mixed sample to the unknown contributors to the mixture
