DNA tests
DNA tests are increasingly used to find out more about one's genetics, family, origins and genetic heritage.
There are different types of tests available online, each with its own purpose and method of analysis.
​
To determine the family ties, it is recommended to choose a biological filiation test. These compare a person's DNA with that of another individual to determine if they are related.
To discover its genetic heritage, a genealogy test is recommended. It allows to know the genetic origins and the ethnic composition of his family.
When choosing a DNA test, it is important to consider the members available for swabs. If the person wishes to perform genetic analysis with a family member, it is recommended to select a test that can be performed with a simple saliva sample.
If family members are geographically distant, an online test is the ideal solution.
Paternity test
Paternity testing is a DNA test that determines whether an individual is the biological father of a child.
It is usually done using a DNA sample taken from both the potential father and the child.
The two samples are then compared to determine if they share significant genetic similarity.
The results of this test are 99.99% reliable and can be used to clarify questions about paternity in family situations..
Prenatal paternity test
The prenatal paternity test is a genetic analysis of DNA which makes it possible to determine the paternity of a child during pregnancy.
There are several types of prenatal paternity tests, but here we present only the non-invasive test with a simple blood test.
The samples are then compared to the DNA of the potential father to determine if he is the biological father of the fetus.
The results of this test are 99.9% reliable and can be obtained in less than 2 weeks. It can be used to clarify questions about paternity in case of doubts during pregnancy.
Sibling test
The sibling test determines whether two people are siblings. It can be carried out using DNA samples taken from the two people in question at the same time.
Samples are compared to determine if they share significant genetic similarity, which indicates sibling kinship.
The results of this test are not 99.99% reliable.and the precision will depend on the genes in common coming from the biological parents.
To improve this precision, it is advisable to add the DNA of the biological mother to the analyses.
Y chromosome test
The Y chromosome test is a genetic test that helps determine a person's chromosomal sex. The Y chromosome is present in males and absent in females.
This test can be performed using a DNA sample taken from blood, oral tissue, or hair. The genes located on the Y chromosome are compared to determine a paternal lineage between two men.
The results of this test are 99.9% reliable and can be used to clarify questions about chromosomal sex or for medical reasons such as genetic care planning.
Mitochondrial DNA test
The mitochondrial DNA test allows you to study the DNA found in the mitochondria, the structures responsible for energy production in cells.
Mitochondrial DNA is passed from mother to child, making it a useful tool for studying maternal lines and genealogy. This test can be performed using a DNA sample taken from saliva only.
Samples are compared to standard genes or another participant to determine similarities and differences.
The results of this test can be used to clarify questions about family history and for medical reasons such as identifying mitochondrial DNA-related diseases.
Parentage Test Grandparents
The grandparent DNA test is an analysis that uses DNA from three generations of the family to determine genetic relatedness.
It can be done using DNA samples taken from grandparents and grandchildren. Samples are compared to determine genetic similarities and differences, which helps determine relatedness.
This test can be used to clarify questions about paternity or maternity, for personal or medical reasons, or to establish inheritance rights. Results can be obtained in a few days.
Avuncular Test
The Avuncular DNA test uses DNA from two generations of the family to determine genetic relatedness.
It can be done through DNA samples taken from the uncle or aunt and their nephew or niece.
Samples are compared to determine genetic similarities and differences, which helps determine relatedness. In order to know if the brother or the sister of the uncle or the aunt are indeed the father or the mother of the tested child.
This test can be used to clarify parentage questions, but it is advisable to include the known parent's DNA for greater accuracy.
X chromosome test
The X chromosome DNA test is a genetic test that helps determine the similarities and differences between DNA located on the X chromosome, one of the 23 pairs of chromosomes found in every cell in our body.
This test can only be performed between siblings with a buccal DNA sample. The samples are compared to determine whether or not they share a common biological father.
The X chromosome is passed from the father to his daughters only. The other X chromosome from the mother. The latter makes it possible to determine, with a reliability of 99%, whether the sisters share the same father.
The results of this test may be available within ten days.
Maternity test
Maternity DNA testing determines the relationship between a mother and her child. It can be done using genetic samples taken from the mother and child, such as saliva, hair, toothbrush or fingernails.
Samples are compared to determine genetic similarities and differences, which helps determine biological parentage.
This test is very reliable at 99.99% for a positive result and it is 100% reliable for a negative result.
The results of this test can be obtained in just a few days and can be very useful during IVF or for questions of family reunification.
Twin test
The DNA test for twinning is a genetic comparison that makes it possible to determine whether two individuals are identical twins or fraternal twins.
It can be performed only on twins or twins; if not, then it is advisable to take the brotherhood test instead.
The samples are used to find out whether the genetic profiles are identical or not. But, the test will not give any information about the relationship between the participants.
This test is very reliable at 99.99% and can be used recreationally and privately to find out the genetic similarities of twins or twins.
Ancestry DNA Test
The genealogy DNA test is a genetic examination that can determine the ethnic origins of individuals and study family lines. The genetic samples used are exclusively buccal swabs.
The samples are compared to a reference database to find out if your DNA has the same mutations of the major human lineages of our civilization.
This test can be used to clarify questions about family history, to establish relationships as part of genealogical research, to make a family tree, to find unknown relatives or for other personal reasons.
The results of this test can take several weeks to obtain and can be compared with those of other individuals to establish relationships.
Baby gender test
The DNA test to determine the sex of the baby is a non-invasive genetic test that can be done during pregnancy. It uses blood samples from the mother to detect DNA from the fetus and determine its sex.
This test is very reliable at more than 99% and can be performed from the 10th week of pregnancy. It offers an alternative to ultrasounds for parents who wish to know the sex of their baby sooner than during a traditional ultrasound. Results can be obtained in less than 2 weeks.
It is important to note that, as with any genetic test we offer, this test is invasive. It is therefore painless and not dangerous for the mother and the child.
Alimentation test
​
The DNA Diet Test analyzes an individual's DNA to understand how their genetics influence their response to food. After a saliva sample is taken, a laboratory generates a personalized report on nutrient digestion and metabolism.
It helps tailor one's diet based on genetic needs and achieve their ideal weight. However, it should not be the sole source of information for building a balanced diet.
The Chimeric DNA Test
A chimera DNA test is a genetic analysis aimed at determining whether a person possesses two different types of DNA in their body.
This phenomenon can occur when cells from two embryos merge to form an individual, resulting in what is known as genetic chimerism.
During the DNA test, samples from different parts of the person's body are compared to check if they have the same genetic profile or not. This helps detect the potential presence of two distinct cell lineages, which can have significant implications for health and genetic identification.
