Step 3: DNA Analysis, Detection

Detection is a complicated and mostly automated process during which the alleles for each locus are determined. The combination of alleles at each locus establishes a profile described by a series of numbers and letters. For each profile developed from a stain or subsample, a series of standard and control samples is also analyzed as a quality control measure.
