STR Analysis

Sorenson Forensics is validated to perform forensic casework using a wide scope of state-of-the-art technology platforms. Our forensic scientists have extensive experience in analyzing a wide range of forensic evidence and recognize that each piece of evidence presents its unique challenges.

The DNA profile generated from STR analysis is a set of numbers that correspond to fragment sizes that are unique to individuals (with the exception of identical twins.)  This power of discrimination makes this analysis a very powerful tool in confidently matching a DNA profile generated from a crime scene to a known individual.

STR Analysis & CODIS

STR is the industry standard for forensic DNA typing and is used for DNA profiles uploaded to the national CODIS database. The DNA profile, also known as a DNA type, is stored in the database. For forensic STR DNA analysis, the DNA profile consists of one or two alleles at the 20 CODIS core loci.
