LEGALLY VALID PATERNITY TEST

At LabGenetics, we carry out legally valid paternity test through DNA testing, starting from €250 and with complete confidentiality.

The results provided are conclusive, reliable, and of high quality, as we are one of the few centers in Spain accredited by ENAC under the UNE-EN ISO/IEC 17025 standard (Download Accreditation), including genetic analysis of skeletal remains and teeth (Download Technical Annex). We are included in the List of Laboratories that comply with the CNUFADN (National Commission for the Forensic Use of DNA) Agreement on Accreditation and Quality Control (2025), both for forensic genetics laboratories operating in the criminal and/or civil fields (Download Criminal–Civil List) and for genetics laboratories participating in the State DNA Bank of victims of the Civil War and the Dictatorship (Download Civil War Victims List).

We have pioneering professionals in the performance of DNA tests for the biological investigation of paternity and maternity, positioning us as one of the leading reference centers in the field of Forensic Genetics at the European level.

In legally valid paternity test, the applicant requires the test results to include the names and identification details of all participants so that they may be used before a Civil Registry or a Court of Justice.

The admissibility of these tests by a court is subject to a proper process for the collection, identification, and shipment of the samples to our facilities. Therefore, all stages of the process prior to analysis must be fully described and recorded within a chain of custody. This chain of custody may only be completed by healthcare or legal professionals, who will identify and safeguard the samples to ensure their authenticity and integrity at all times.

Taking and sending samples

Those involved in the test must come to our facilities or to any of our collaborating centres (distributed throughout the national territory) where they can have the samples taken. Contact us and we will indicate the nearest collaborating centre. In addition, if necessary, our professionals can travel to take the sample at home.

In order to take the sample and complete the chain of custody, participants in the test must provide:
