Mitotyping Technologies - The clear choice for forensic mitochondrial DNA and STR analysis.

Accredited for human identity testing by ASCLD/LAB since 2001 and permitted in forensic identity by New York State.

We are also permitted in the area of forensic identity by the New York State Department of Health.

We recover mtDNA from over 95.5% of hairs.

Please see our January 2005 publication in Journal of Forensic Sciences about our five years of casework experience with hair analysis. Our protocols for working with degraded DNA give us a superior recovery rate for mtDNA in challenged samples.
