Genetic trace

Please request a personalized kit for the test.

Obtaining the sample at home.

DNA contains all the information needed for the development of live organisms. Individuals from the same species share a big part of the DNA sequence, but there are certain regions highly variable that are specific of each subject. These areas of the genome are called polymorphisms or genetic markers and they are use for the identification of people, since it is very unlikely that two human beings not related to each other could share the same genetic markers. The group of polymorphisms specific of each person is known as genetic profile.

The individual genetic profile allows us to identify each person, except in the case of having a monozygotic twin brother, since in this case they share the same DNA sequence. The genetic profile characterizes each individual the same or even better than their own fingerprints, this is why it is called genetic trace. Its advantage is that is more precise than other identification methods. Also, DNA is found in each and every single cell of the human body, therefore it can be obtained from any biological sample. The genetic trace is invariable and unique along a person’s life.

The genetic trace is used in forensic medicine in the identification of human remains, paternity test or relationship, compatibility in organ donation... etc.

The situations when doing this kind of study could be very useful, among those, we list some below:

1. To provide a standard (a reference) for the comparison and identification of people in high risk employment such as soldiers, firemen and policemen.
2. To have the genetic profile for the identification in case of an accident, fire or disaster.
3. To have the genetic profile for future paternity or relationship tests. o parentesco.
4. To identify adopted children or those conceived through IVF techniques using donated gametes. In these cases children do not share the genetic code of their parents, so the biological identification cannot be used on the DNA studies to be compared with the parents. To have the genetic trace taken is usually more useful in the circumstances mention earlier (accidents, kidnapping, fire, or situations when there could be doubts about the identification of a person).

Finally, as an alternative service to obtaining the genetic trace of an individual, his own DNA could be kept for future usage:

1. In the case of a genetic illness diagnosed.
2. Hereditary genetic illnesses prevention.
3. Solution of paternity disputes.
4. Comparison and identification of people in high risk professions (soldiers, firemen, policemen).
5. Comparison and identification of people in case of accident.

HOW TO DO IT AT HOME?

The procedure is very easy. On the kit that you will receive, you will find sterile cotton buds, with which you would need to rub the internal side of the mouth of the subjects involve. Use the samples carefully. Use protection to touch the cotton buds. Once you have taken the samples and you have packed them properly under the directions given, you should send them to us with the corresponding forms.

If you would like the results to have legal validity, the samples have to be taken by professionals at one of our clinics, so the origin of the samples can be proven.
