A report contains the conclusions that an analyst has made based on the scientific data and established interpretation procedures.

An inclusion or match is reported when all the loci from which a result is obtained match between a questioned sample and a known sample. With the exception of paternity testing, if the result for even one locus does not match and is discordant, an exclusion is declared. A minimum of a two-locus exclusion is needed in order to declare an exclusion for paternity.
