Mitochondrial DNA Test

In order to determine a maternal lineage, the laboratory analyzes the Mitochondrial DNA transmitted only by the mother to all her children .

In this context all individuals from this line share the same Mitochondrial DNA , but unfortunately the hereditary line breaks with a father. Man not being able to transmit this DNA.  

Mitochondrial DNA is a hereditary DNA which has the particularity of not suffering from the wear and tear of time and thus does not present any mutation through several generations.

Maternal lineage testing determines whether genes in Mitochondrial DNA are alike or not , and the conclusion that the individuals tested may be related through a common female ancestor.  

On the other hand, the analysis of Mitochondrial DNA cannot distinguish a specific relationship between women belonging to the same maternal line .

For example, the test will not be able to define motherhood between an alleged mother and an aunt if the two share the same Mitochondrial DNA.

However, it can be useful in excluding a mother from an alleged biological relationship. 

If in your search for maternity, the doubt is about presumed mothers coming from the same family. Then the Mitochondrial DNA test is not suitable for your situation . Please  in this case consult  our guide to maternity research to find a suitable test.

DNA relationship testing helps compare the genetic profile of two or more people to determine a common biological inheritance. Generally speaking, the test highlights the similarities and differences that make up your genetic makeup and assesses your match rate in order to give you results that match your relationship search.

In any case, this study cannot be established without putting different individuals in comparison, because your DNA is unique and does not contain the genetic profiles of your family, but only its heritage.

Do you want to remove any doubt about your biological origin or that of a loved one? But you don't know which test is best suited for your situation, follow our guide !! Information on DNA test we propose to orientate on possible tests currently putting you in the position of a paternity or maternity. Go ahead, it's simple and free and will allow you to already have solid information before contacting the laboratory that corresponds to you.

The DNA Relationship Test

Mitochondrial DNA analysis can also be used for genealogical research on the origins of your maternal ancestors.

DNA genealogy testing examines specific locations in your DNA to estimate ancestral genetic relationships. It allows you to compare and integrate your genetic profile into a database that lists and uses different ethnic groups of reference , composed of people tested and whose previous origins are known.

There are three main types of genealogical DNA testing , each examining a different part of the genome and useful for different types of genealogy research:

In order to have information on your origins :


- Know your ethnic percentage

-  To find  information on the origin of your family

- Understanding population migration


You wish to complete the archives  genealogical  of your family :  


- Improve your classic genealogy research

- Discover and identify genetic matches

- Find family members

- Add your genetic profile to a database


The DNA genealogy test will not give you with certainty and accuracy a biological relationship between family members . It can give you a more or less distant relationship percentage that you must confirm with a relationship test in order to guarantee the biological connection.

The Mitochondrial DNA genealogical test can be used to determine the origins of maternal ancestry and trace the  ancestors  family on your mother's side.


In addition to providing you with important information in your genealogical research, this DNA test gives you access to:  


- Your direct maternal line and your geographical origins

- Relationships with people who have the same DNA

- The ancient migration paths of your female ancestors

- Your maternal affiliation to the haplogroup


Mitochondrial DNA allows lineage investigation  from your mother very precisely. So this process can help you find parents who are unknown or lost to follow-up.

It is possible to order a genealogy test with the mitochondria:

- This test is done individually

- With a saliva sample only

- The results are available in English

- Analyzes are ready in 4 - 5 weeks

Maternal line test

The genealogy of Mitochondrial DNA

Mitochondrial DNA testing is a genetic comparison between two individuals to determine a maternal relationship.

mitochondria  is an autonomous structure present in all the  cells  human. This component has the particularity of possessing its own DNA, and its function is to provide  energy  to the cell allowing it to become completely autonomous in turn.

The mitochondrion and therefore its mitochondrial DNA is transmitted only by the mother to all her children . This transmission is completely identical from generation to  generation  because mitochondrial DNA mutations are  extremely rare.

The mitochondrial DNA test consists of analyzing the markers of this DNA, in order to define your maternal line with great precision. It can be done by men and women for genealogical research as well as for a relationship test.

The mitochondrial DNA test can be done exclusively with oral samples.

What is a Mitochondrial DNA test ?

The genetic analysis of  DNA  Mitochondrial in order to determine the maternal lineage and the search for a maternity can be useful in several constructions according to the participants:

- Genetic analysis between sisters and/or half-sisters (different biological father)

- Genetic analysis between cousins (on the maternal side: the children of the aunt)

- Genetic analysis between a niece and an aunt  (the aunt must have the same biological mother as the mother sought)

- Genetic analysis between grandchildren and their maternal grandmother

Under what condition can we define a maternal line ?


Consent is the agreement you give to the laboratory to use your DNA for the purpose of carrying out a genetic analysis. It is mandatory if you want to do a Mitochondrial DNA test. Consent can only be given explicitly by an adult and fully lucid person. This agreement must be in writing after having received informed information about the results of the test, by a contract or a consent form.


It is against the law to do a DNA test without the person's consent.

For minors, consent must be provided by one of the legal parents.

DNA test procedure


Mitochondrial DNA testing can be done with:

- Saliva samples  (Sterile buccal swabs)


Attention, it is not possible to carry out this test with another type of sample!

What type of sample used for the test ?

You can do a DNA test to find out the parentage at home in a private setting . The order can be made directly on the internet from your home in order to receive the sampling equipment at home. 

Unfortunately it is still impossible to obtain
a DNA test in a pharmacy, moreover only a laboratory with genetic analysis equipment and accredited by international standards can provide the result for a DNA test.

How to do a DNA test between grandchildren and grandparents?

Maternal Line Participants


- The grandmother can participate in the test


The grandmother must be the alleged mother's biological mother

A Mitochondrial test with the grandmother will determine whether or not the maternal line between the mother and her children


- Technically the Mitochondrial DNA test can be done with the mother.


But for reasons of reliability and cost, if the mother is available we recommend the maternity test.


- One or more uncle and aunt can participate in the test

Uncle and/or aunt must have the same biological mother as the alleged mother

A Mitochondrial test with the uncle and/or aunt will determine whether or not the maternal line between the mother and her children


- One or more cousins can participate in the test

The mother of the cousins must be the biological sister of the alleged mother

A Mitochondrial DNA test with cousins will determine whether or not the maternal line between the mother and her children


- One or more  siblings can participate in the test

The test can be done between half-siblings

Mitochondrial DNA test Results

- 20 to 30  days using buccal swabs for all participants



This period is calculated from the moment your  samples arrive at the laboratory. Transport time is not taken into account.

What are the analysis times for a maternal line test 

The reliability and authenticity of the test  DNA depends on several factors:

- The quality of the samples

- Laboratory accreditation

- The choice of the test according to the family situation

How Reliable Are Mitochondrial DNA Results ?

The quality of the DNA will depend on the collection and storage of the samples . It is therefore important to follow the instructions of the laboratory in order to ensure that you receive results.

Accredited laboratories meet the requirements relating to the analysis process, the management of resources and equipment, the impartiality and confidentiality of information. For a DNA test with grandparents the laboratory must have ISO 17025 accreditation .

The results are presented in the form of a table:

- Each  column  corresponding to a participant

- Each line has a compared gene

- The composition of the gene is represented by one or two digits / per person

How to read the results of the mitochondria test ?

DNA analysis is a direct relationship test. The genetic laboratory compares the profile of each individual to determine whether they are similar or not. So the answer is either positive or negative, there is no room for doubt.

It is not possible to obtain inconclusive results .

Genetic laboratory

The choice of the laboratory is a very important step when you want to do a DNA test. You should know that not all laboratories offer the same services and depending on several factors it is better to make the choice that suits you.

You must choose a laboratory according to:

- Your family situation and available participants

- The confidence that the laboratory inspires through customer feedback

- The transparency of the company concerning its activities and your expectations

Search for paternity between siblings

With the maternity test you can compare your genetic profile directly with that of an alleged mother to define or not a biological relationship.

Paternity search between sisters

The analysis of the X chromosome makes it possible to define whether the two sisters share the same paternal X chromosome. For this it is mandatory that the sisters share the same biological mother
