Amplification (nDNA only)

Amplification of STR areas of DNA by the polymerase chain reaction (PCR) is currently the most common DNA forensic technique being used to generate a DNA profile. A word of caution: not all evidence yields sufficient DNA to produce a profile, nor does every sample provide interpretable results at every DNA area (locus) at which amplification is attempted by the lab.
