GEDNAP

GEDNAP is the acronym for German DNA profiling and was in the early 1990s based on EDNAP ( European DNA profiling , a working group of the International Society for Forensic Genetics for the first time [ISFG]) as part of the track commission of, the joint commission forensic medical and forensic Institutes in Germany, organized trace ring tests used for quality control in forensic trace research and DNA analysis .

Initially, the interlaboratory tests were carried out with classical serological systems, which were organized by the forensic medicine institute of the Hannover Medical School . After the introduction of the DNA systems, the Institute for Forensic Medicine Münster, under the leadership of Bernd Brinkmann at the time, was commissioned by the trace commission to carry out the DNA round robin tests. Even after his retirement in 2007, Brinkmann, as head of the Institute for Forensic Genetics , carries out the GEDNAP ring tests on behalf of the German Trace Commission .

The GEDNAP interlaboratory comparisons are organized to give the participants the opportunity to undergo regular external quality control, the result of which is documented by an assessed certificate. With this certificate, the participant can document that he has successfully typed a specified number of traces and / or reference samples for a number of genetic systems named therein.

Two round robin tests are held each year. The participants receive three comparison samples and four artificially created traces, which in principle should simulate all traces occurring in the casework. This can be mixed tracks of a maximum of three people. As trace types are saliva , blood and sperm traces (as well as mixtures of these trace types) into consideration.

While the participants originally came from German-speaking countries, more and more participants from other European countries have been added in recent years, not least through the members of the European Network of Forensic Science Institute (ENFSI), who have adopted the GEDNAP round-robin tests as their official round-robin test . The participants are laboratories from the fields of forensics and genetics. Successful participation is z. B. also a prerequisite for the accreditation according to DIN EN ISO / IEC 17025, which is carried out and monitored in Germany by the German accreditation body .
