About the Mitochondrial DNA Test
The Mitochondrial DNA sequence variation is passed from females to their children and has a relatively infrequent mutation rate, thus it remains the same through many generations. (Males do not pass the X-SV they inherited from their mother to their children). Results for this test are ready in 14-16 working days from the receipt of samples at our laboratory.
This test focuses on the Mitochondrial DNA and results in a unique X-SV profile for each individual tested. It is important to note that this test will not differentiate women that are in the same maternal lineage or children with the same mother.
For example, if a female Child “A” and her alleged half-brother, Child “B” (Child “B” having a different father than Child “A”) want to know if they have the same maternal biological grandmother, and they have the same X-SV profile, it is very likely that they are of the same maternal lineage. If the X-SV profiles do not match, then they neither share the same maternal biological grandmother, nor do they share the same maternal lineage.
Samples for our mitochondrial DNA test are collected using our specially designed home DNA sample collection kit. The kit will contain:
- 4 mouth swabs for every test participant
- Instructions about how to collect the samples and precautions
- Consent forms
- Pre-addressed return envelope
Results for this test take 14-16 business days. It is important to note that we can only guarantee standard result turnaround time when testing takes place solely using mouth swab samples. Using a discreet sample, such as hair, blood or a used Kleenex, for your mitochondrial DNA test may lead to an increase in turnaround time.

An Important Note about MtDNA Testing
*Note that results for this test will either confirm or exclude a shared maternal line between the individuals tested. The results will not spell out the exact relationship between the individuals tested or how they are related. If individuals tested want to know if they share the same mother, they will need to carry out a maternity test.
