DNA Forensic

We have been working for German law enforcement agencies since 1998. The same year the Federal Criminal Police Office's (BKA) DNA Analysis Database (DAD), which collects and analyzes DNA profiles of offenders and crime scenes, has been introduced. The genetic fingerprints or DNA profiles created for the DAD can provide crucial clues or trace-makers for "trace-person matches" or link different crime scenes as "trace-trace matches."

Trace Analysis

The DNA analysis of human traces is based on the question of whether a "trace" was "laid" by a human, and if so, by whom (proof of identity) or by whom not (exclusion of identity). Sample materials include, for example, evidence such as clothing (gloves, hats, etc.), cigarette butts, chewing gum, tissues, drinking vessels, blood, saliva, and semen traces, as well as burglary tools and weapons—in short, any objects that came into contact with the "trace-maker." Isolation is achieved under a microscope or by taking samples with DNA-free cotton swabs. Human remains such as bones, body parts, or tissue are also processed by the laboratory as "traces."

Mass DNA screening of up to several thousand people is ordered by the police in cases of serious crimes where the perpetrator has left traces at the crime scene and the perpetrator profile could be narrowed down. Through a high degree of automation, efficient processes, and rigorous quality management, we achieve a very high throughput of several hundred samples per day. Therefore, we are a reliable partner, even for large sample volumes under tight deadlines. We also regularly work for companies, industry, and private individuals. In these cases, it is important to ensure compliance with the Genetic Diagnostics Act (GenDG).

Sample Collection via Buccal Swabs

Buccal swabs, also known as "saliva samples" or "personal samples," are taken painlessly and easily from the mouth using cotton swabs. The DNA profiles obtained from these samples are used to identify individuals who left traces, to detect contamination, or, according to the Code of Criminal Procedure (StPO), to add offenders to the BKA's DNA Analysis Database (DAD). Saliva samples are also used for paternity tests, parentage analyses, and genetic analyses. In Germany, we are the leading laboratory for creating DNA profiles from saliva samples.

Identification of Persons

Beyond police work, the identification of human traces is required, for example, in cases of contamination in industrial processes or products. Human hair or cigarette butts in pharmaceutical or food production areas are typical examples. We also conduct tests on behalf of pharmaceutical and biotech companies or research institutes to ensure the correct matching of blood and tissue samples (sample mix-ups).

Disasters, Catastrophes, Accidents

In plane crashes, natural disasters, and other accidents with a large number of fatalities, the rapid and reliable identification of victims is essential. Relatives, insurance companies, and stakeholders need certainty about the victims' identities. The most reliable method of identification is DNA fingerprinting. Even if a "reference sample" from the individual is unavailable, a reliable identification can be achieved through comparison with samples from close relatives, through ancestry analysis. Eurofins Forensics, with its experience and size, can provide rapid and professional support in disaster situations. We can provide security to relatives, airlines, authorities, and insurance companies when identifying individuals.
