Mitochondrial DNA Analysis – A Different Approach to Crime Solving
Bio-Synthesis, Inc. begins Mitochondrial DNA Testing or MtDNA, making it one of only a handful of labs to perfect the technology. MtDNA Testing allows Forensic scientist to get a profile from samples that are old or possibly damaged, where the usual technique may not be effective....

Maternal lineage
When to use mtDNA?

Maternity Testing
mtDNA is passed from a mother to her children. So, by analyzing the mtDNA of a mother and child, maternity can be confirmed.

Sibling Studies
All maternal relatives have the same mtDNA. Siblings have the exact same mtDNA as their biological mother. mtDNA testing can prove if two people share the same mother.

Genealogy Studies
Since mtDNA is found in old to ancient remains, mtDNA profiles can be traced to tens of thousands of years ago..

Forensic Case Work
mtDNA can be extracted from hair, bones and teeth. Old, unidentified remains can be compared to the mtDNA profile(s) of available, suspected maternal relatives. This has proven to be extremely useful in cases involving compromised DNA samples such as those found in mass disasters, missing persons investigations, or cases involving limited samples of questionable quality.

How to start?

Step 1: Fill out our mtDNA Test Application and fax it to 972-420-0442 or call 1-800-DNA-EXAM (800-362-3926) to request a quote for your DNA testing needs.

Step 2:

We will provide a quote with all test fees and any additional fees that may incur due to special situations. Upon agreement, samples shall be prepared and submitted to our lab.


Step 3: Once samples are received, analysis will begin. Average turnaround is approximately two weeks, at which point a certified copy of the results will be sent to you. We also include a letter of explanation for your convenience.
MtDNA testing is a powerful technology, which has received much recognition within the last decade. The DNA Identity Testing Center at Bio-Synthesis, Inc. (BSI) is currently sequencing mtDNA samples for maternal lineage confirmation and criminal investigations. For more information about mtDNA analysis, contact us now!

What is mtDNA analysis?

There are two kinds of DNA in the cell – nuclear DNA and mitochondrial DNA (mtDNA). Within the nucleus of any (nucleated) human cell, you can expect to find hundreds of copies of mtDNA, and only two copies of nuclear DNA. mtDNA analysis is often the preferred method used by forensic scientists. Because mitochondria are structurally strong and protect the DNA they contain, mtDNA can be extracted from old to ancient remains, including hair, bones and teeth. It is passed from generation to generation along maternal lineage. There is no change in mtDNA from mother to offspring. mtDNA allows DNA profiles to be obtained from evidence that may not be suitable for other analysis.

A DNA sample that is old may not have nuclear matter left in the cell, which can impede on conventional, nuclear DNA analysis. MtDNA, however, is extremely hardy and abundant and will often surpass nuclear DNA in terms of viability.

mtDNA analysis is also extremely useful for degraded evidence or that which may have been improperly stored. Sometimes, these degraded samples are unable to yield results with standard analysis techniques.

"I just want to thank the continued professional and courteous service your Customer Service team provided me during the stressful waiting period for the DNA results. I contacted both your phone support and instant chat support teams at least twice and received concerned support each time. Never did I feel like they thought I might be calling too much and needed to be more patient. I truly appreciate their consideration and patience during this time."
