DNA tests cannot be done just any old way. Although it is very easy to get a DNA test on the internet, you should be aware that DNA tests sold on the internet are illegal and subject to fines in some countries, like France. For this reason, it is preferable to go to a place likeĀ to perform a dna test. However, a court dna test may be authorized in a legal proceeding for one of the following reasons: to dispute or establish parentage, to establish a person’s identity, to remove or receive a financial contribution (also known as subsidies), etc. A DNA test can also be performed upon medical request in order to:

  • Establish, refute or confirm the diagnosis of a genetic disease;
  • Search for the genetic characteristics at the origin of a disease;
  • Adapt the treatment of a person according to his or her genetic characteristics.

How to perform a DNA test on medical request?

When a DNA test is carried out at the request of a doctor, the subject’s consent must be obtained in writing before the test is carried out, after the person has been duly informed of its purpose and nature. The consent must mention the purpose of the test, as it can be revoked without form and at any time. The analyses must be carried out by authorized laboratories and the results must first be communicated to the prescribing physician who then informs the patient, unless the latter has formally expressed his refusal to know the content. Outside this framework, a DNA test can be performed by sending dedicated test kits purchased on the internet. After having made the purchase online, it takes 3 to 5 working days to receive the test kit at home. And after collecting the DNA (saliva, hair, skin or body fluids), the user must send the sample to the laboratory. Results are available online within 2-5 weeks in the user’s personal account.

Types of DNA tests

There are different types of DNA tests: the fraternity test, the maternity test, the paternity test ( although it is impossible to do a paternity test without the prior authorization of a judge in some countries such as France), the prenatal paternity test, the mtDNA (Mitochondrial) test, the Y-chromosome test, the genealogy test, the fetal trisomy test and the zygosity test. All of these types of DNA tests except for the prenatal paternity test can be performed from a buccal swab, as the child in question is not yet born.
