GEDNAP is the acronym for German DNA Profiling and was used in the early nineties in analogy to EDNAP (European DNA Profiling, a working group of the International Society for Forensic Genetics (ISFG) for the first time in the course of the proficiency tests organized by the German Stain Commission, a Joint Commission of University Institutes of Legal Medicine and Police Institutes of Forensic Sciences in Germany.
After his retirement in 2007 Bernd Brinkmann founded the Institute of Forensic Genetics, serving as managing director of the GEDNAP Proficiency test program.

The results of the GEDNAP proficiency testing exercises are presented at the annually held German Stain Workshops.
