Our paternity tests are carried out by experienced, skilled personnel. Our laboratory is ISO 17025 accredited by the national accreditation body for the Federal Republic of Germany. We regularly achieve quality certificates from independent organisations (German Society for Legal Medicine, International Society of Forensic Genetics). As we are not an agent for paternity tests, you can discuss your specific testing requirements directly with our DNA testing experts.
