Performing a DNA test is a fairly common procedure among those, who wish to prove the paternity of their son or daughter, know the kinship between individuals, tests for surrogate pregnancy or for more and more genetic tests. The nature of this clinical analysis can be merely informative and personal, as well as legislative or judicial.
Depending on the purpose and destination of these tests, the application procedure and the implementation procedure will vary and will be carried out by means of specific conditions.
The differences between informative and legal DNA tests
The most notable changes and differences between the judicial and private DNA tests, in this sense, are the following:
Specific or informative DNA tests: in them, the names of those involved are not included in the report. The interested party can perform the test at home, without having to travel to a laboratory or medical center. They do not have any judicial validity.

Legal DNA tests: they are requested by means of an expert report and they are supervised, carried out and guarded by judicial and health personnel. Each one of them must be certified for it. On the other hand, results reports include the names of those involved in the test.
The legal DNA tests are usually those that involve a more strict and formal process, since a 100% reliable result is required and without errors. However, the steps to follow to realize them are the same in both.
Collect the sample:
The samples required must be biological and belong to each of the subjects whose relationship must be analyzed. The oral smear has become the star process to collect samples. This responds to a process of direct extraction of oral fluids.
Analyze the sample
Once in the laboratory, the sample is analyzed and the DNA is extracted, as well as purified. After that and following the process called Polymerase Chain Reaction Technique (PCR), the DNA is subjected to an amplification to increase the presence of the specific sections of each individual.
Examine the sections of the DNA
Once the sections and the structure of the DNA chain of the subjects have been obtained, each and every one of these parts must be examined – conscientiously. Thanks to this, the geneticist will obtain greater security in their results. As an example, for a paternity test, the professional must make sure that the child’s DNA chain matches the father’s and the mother’s 50%.
DNA test blood
As can be seen, the nature of the DNA tests is extremely binding and relevant in terms of the procedure. Many patients and users who carry out this request do not usually consider this distinction. Therefore, doubts and mistakes are very common. Broadly speaking, you should always bear in mind that a DNA legal test has a court as a recipient. This implies that its result requires guarantees and procedures that are much more exact, assured and rigorous, since the jury’s decision will depend on it.
