Mitochondrial DNA Test

A mitochondrial DNA test (mtDNA test) determines the probability of the existence of a relationship on the maternal side.

As the transmission is complete, all the children of this mother and her grandchildren will have the same mitochondrial DNA.

Sibling DNA Test

Doubts about a brother or sister? Do you share the same parents? A Sibling DNA test can confirm a biological relationship between brothers and sisters.

Order a Paternity Test

Why a DNA Test?

- To reassure you about the origin of a loved one: child, parent, grandparent.
- You suspect a baby exchange or error during a medically assisted procreation.
- To get rid of doubt before initiating legal proceedings for paternity, to obtain rights of custody, etc.

Oral or Blood?

DNA is the same in every cell of our body. A laboratory can collect DNA from various samples like blood drops, hairs and skin tissue.

A mouth swab is the easiest and cheapest way to get DNA samples from a person, especially when it involves small children.

A DNA Test at Home?

A mouth swab is enough to do a DNA test (except for prenatal paternity testing). This procedure can be done without stress for both adults and infants.
Samples are taken at home, painless, using a sterile cotton swab that is rubbed in the mouth against the inside of the cheek.
Recovering a little saliva and a few cells is enough for the DNA test. Click for more information.
