A DNA search involves a genetic test to prove the relationship between two or more people. In terms of genetic analysis, the paternity test is the most common. It is performed from a saliva sample or a blood test to determine the paternal lineage via the chromosomes. Today, DNA testing is becoming more and more accessible thanks to the test kits available on the Internet. However, in France, the performance of genetic analysis outside of a legal procedure is strictly forbidden under penalty of fine and imprisonment. Why resort to a DNA test? How is this test carried out and how much does it cost?
What are the different reasons for genetic testing?
Performing a DNA test is not a trivial act. It allows not only to find the origins by the comparison of 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 about their ancestors. Indeed, genetic tests allow to compare the genetic sequences. Thus, it is the best solution to trace his origins but also to prove the paternity of a man. The results of the tests can remove the doubt about the existence of genetic disease or the recognition of paternity. Moreover, the genetic evidence is indisputable. The price of a DNA test varies according to the reliability of the results and the laboratories involved.
Take a genetic test to find your origins
DNA analysis can be carried out within the framework of legal proceedings, notably for thepaternity suit. Also known as ancestry testing, this type of testing provides more information about ethnic origins but also about hereditary diseases through genetic testing. In addition, 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 accredited and qualified DNA expertise laboratory.
How does a DNA test work?
The process of a paternity test begins with the collection of a DNA sample from the subjects involved. This sample is generally taken from the mouth. In fact, this consists of a swab in the mouth using a cotton swab to obtain saliva samples. In the case where saliva sampling is impossible, it is common to take a DNA sample by :
- genetic fingerprints.
Afterwards, these DNA samples are given to the laboratory for further research on the genetic heritage and compare the genetic markers. Once the examination is completed, the results of the test will be communicated to the individuals 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 performed, the laboratory and the length of time the result is expected.
Compare the DNA profiles of a child and a man
For a pregnant woman at search for the biological father of his child, it is possible to do a DNA test at the birth of the baby. This test requires a blood sample from the child or a buccal swab as well as saliva samples from the presumed father to compare the genetic and biological data. It costs about 80 euros for this test. On the other hand, to proceed to a test during the pregnancy presents risks for the baby.
DNA test according to the sample taken
Paternity tests performed on buccal samples are considered standard DNA testing. For any other form of DNA collection from a source other than saliva, the test is considered non-standard. For this purpose, the samples must be submitted to viability test at a price of 90 euros. The purpose of this step is to extract genetic traces to perform the test.
