Paternity test and identification

The paternity test enables the son or daughter to know who the biological father or mother is. On the other hand, the parental test allows to identify other familiar relations such as siblings, grandfathers, uncles, cousins, etc. 

The paternity and parental tests consist in a genetic study of each individual in order to obtain the so-called genetic profile or genetic fingerprint. The comparison of the genetic profiles of each individual allows the identification of the relation between them.

For questions or to request an appointment, call us or write us by Whatsapp and our specialists will inform you with absolute confidentiality.

At home

We will send a "sample collection kit" with the instructions and the material to your address. Follow the instructions and, once you have it ready, you just need to send it to us by post or courier. 

Samples will be identified with a numbering. Only you will know whose sample is it. These tests don't have legal validity.

In our facilities

We can do the saliva sampling in our facilities. Our staff will be pleased to provide you with a professional service by ensuring to let you feel at ease, in a confidential environment and that the sample taking meets all the technical requirements.

If you need the test to have legal validity, it has to be carried out in a collaborator lab or in our facilities.

In a collaborator lab

The sample can be collected in a collaborator lab close to your home. In this way, it wil be both convenient, as you don't need to come all over our facilities, and safe since you will do it in a trusted center. Check our collaborator lab network

If you need the test to have legal validity, it has to be carried out in a collaborator lab or in our facilities.

In your medical consultation

In certain cases the sample has to be collected in a medical consultation. This happens when we need to use a sample of amniotic fluid or chorionic villus. 

We will contact your doctor to inform him about the preservation and transport of the sample. 

Anonymous Paternity Test

To take an anonymous test (judicially invalid), you can take the sample by yourself in your house.

We will send you an envelope to your address with the instructions and the required material. Follow the instructions and when you'll have the sample ready, you only need to resend it to us by post or courier service.  
The sample will be identified with a numbering. Only you will know whose the sample is.  
The anonymous test cannot be used judicially, however, taking it is not illegal at all.

Judicial Paternity Test

To take a test with legal validity the following conditions must be fullfilled:

1) Sample taking: the taking and custodity of the sample has to be certified by our laboratory staff or by a collaborator laboratory of your city.

2) Documentation: the following documentation must be provided in order to identify the involved individuals and guarantee the sample's custodity.

Required documentation:

1) DNI, NIE or (original) passport. It must be provided by all the involved individuals (including minors' tutors and minors if they dispose of any)..

2) Family Book or other original document that proves the parental authority over the involved minors.

3) Original picture  of the minors (in case they don't dispose of any document).

4) The request document . it has to be signed by all the involved adults (including the minors' tutors).            

5) Identification document and the cutodity chain of the samples. Filled in the laboratory.


Different types of samples can be used: saliva, blood, semen, amniotic liquid, cigarette butts, personal items (toothbrush, glasses), personal hygiene items, hairs (with follicle), human rests, etc. Each involved individual's sample is required, in other words, at least the father's and son's. If you wish to take a legal valid test, the sample taking has to be carried out in a collaborator center.

From each sample we obtain the genetic profile and through the comparison of both, the paternity is identified.

Additional costs: The final cost of the test rises if more individuals are added to the study (other sons/daughters, the mother, etc). The submission of samples other than saliva can affect the price, therefore if that's the case, we recommend to request a quote in advance. Please ask about legal validity tests prices. 

Delivery term and confidentiality

The report has to be delivered only to the authorized person. They are not provided by telephone or to unauthorized persons. Consult the deadline for delivery of results. Other samples than oral samples (hairs, toothbrushes, personal utensils, condoms, etc.) may have a longer delivery time due to technical issues.

Moreover, our report includes an hologram for security scope that makes it practically unforgeable. This measure provides greater confidence to the document in the case of a judicial use.

¿What is the genetic profile?

The genetic profile is the fundamental concept in the human indentification. It consists in a serie formed by different pairs numbers that constitutes a personal combination exclusive to each individual. Each pair of numbers represents the two alleles that an individual has in the same gene.

Usually it uses 15 polymorphic (variable) genes a part from the amelogenin (sexual marker). In this way different pairs of numbers allow the unequivocal identification of a person.

Comparison of the genetic profiles of a woman and a child (two different cases)

Case 1: the comparison of the two genetic profiles shows compatibility in all the genes (signed with red circles). This case shows a real relation between mother and son.

Case 2: the comparison of the two genetic profiles shows compatibility in some genes that has occurred by chance (signed with red circles). However, this sample shows incompatibility in 5 genes (signed with the red cells. This case shows the lack of the relation between mother and son..

Results quality 

We use the genetic identification technology that is usually used by the scientific police in many countries, therefore, the result is technically guaranteed. Our procediments are certified by the ISO 9001:2008. 

Our center carries out tests of genetic identification to study the paternity and the parentality between idividuals by using the recommendations of the International Society of Forensic Genetics (GHEP-ISFG). Likewise every year we realize the paternity excercise of the International Society of Forensic Genetics achieving excellent results.

Stolen children

Progenie molecular has developped a free database with genetic profiles of people who are looking for a missing relative.

You can register his/her genetic profile obtained from another center to let us include it in our database so we can compare it with the existing profiles.
