A DNA search involves a genetic examination to prove the relationship between two or more people. When it comes to genetic analyses, the paternity test is the most common. It is carried out using a saliva sample or a blood test to determine the paternal lineage via the chromosomes. Today, taking a DNA test is becoming more and more accessible thanks to the test kits offered on the Internet. However, in France, carrying out genetic analysis outside of legal proceedings is strictly prohibited under penalty of fines and imprisonment. Why use a DNA test? How is this test carried out and what is its cost?
What are the different reasons for carrying out a genetic test?
Performing a DNA test is not a trivial act. It not only allows us to find the origins by comparing the genetic characteristics but also to determine a genetic disease from grandparents or ancestral diseases that pass from generation to generation. Many people also decide to use DNA testing to find out their ancestors. Indeed, genetic tests make it possible to compare the genetic sequences. Thus, it is the best solution to go back to its origins but also to prove the paternity of a man. The test results can remove doubt about the existence of a genetic disease or the recognition of paternity. Moreover, the genetic evidence is indisputable. THE price of a DNA test varies in particular depending on the reliability of the results and the laboratories involved.
Take a genetic test to find your origins
DNA analyzes can be carried out as part of legal proceedings, particularly for thepaternity search action. Also called ancestor testing, this type of test provides more information on ethnic origins but also hereditary diseases thanks to genetic screening. Additionally, the family history is much clearer by establishing a family tree traditional. To find the origins via a DNA test, it is advisable to trust an approved and qualified DNA expertise laboratory.
How is a DNA test carried out?
The process of a paternity test begins by taking a DNA sample from the subjects involved. This sample generally concerns the oral swab. In fact, this consists of a swab in the mouth using a cotton swab to obtain saliva samples. If saliva sampling is impossible, it is common to take a DNA sample by:
- the blood ;
- nails ;
- the hair ;
- genetic fingerprints.
Subsequently, these DNA samples are given to the laboratory to do in-depth research on the genetic patrimony and compare the genetic markers. Once the examination is finished, the test results will be communicated to the persons concerned.
How much does a DNA test cost?
In general, the price of a standard DNA test is around 149 euros. However, this can vary depending on several criteria, namely the type of DNA test to be carried out, the laboratory and the duration of waiting for the result.
Compare the DNA profiles of a child and a man
For a pregnant woman search for biological father of your child, it is possible to do a DNA test when the baby is born. This test requires a blood test from the child or a mouth swab as well as saliva samples from the presumed father for comparison of the genetic and biological data. It costs around 80 euros for this test. Furthermore, taking a test during pregnancy presents risks for the baby.
DNA test depending on the sample taken
Paternity tests performed on oral samples are considered standard DNA analyses. For any other form of DNA sampling of origin different from saliva sampling, the test is said to be non-standard. For this, the samples must be submitted to viability test at a price of 90 euros. This step aims to extract genetic traces allowing the test to be carried out.
