Certagen, VHL and VHP are accredited for DNA parentage testing with STRs by the International Committee for Animal Recording (ICAR). VHL is additionally accredited by ICAR for parentage verifications based on SNPs. This accreditation recognizes our long history of having provided high-level services in accordance with extremely stringent quality standards. This accreditation is essential for producing accurate and reproducible results.


Certagen, VHL and VHP are members of the International Society for Animal Genetics (ISAG). ISAG’s biannual international conferences offer scientists the opportunity to exchange ideas on a variety of topics. The result has been the creation of an international nomenclature that permits affiliated laboratories to exchange results. International ring tests are performed biannually for a variety of animal species.

What do these accreditations mean to you?
All documents, produced in processing of the orders (e.g. order forms, also technical records) must be archived in a clearly defined way. By this means, it is still reproducible after years, which member of our staff analysed the respective sample when on which machine and if any characteristic has been observed.
We must prove the accuracy of our assessments obtained from our tests regularly. As a rule, we do this by annual laboratory comparison tests. In these comparison tests, the participating labs exchange samples, test them independently and compare the respective results. We can only keep our accreditation, when we are able to prove in these tests, that our procedures provide accurate results.
Our methods and results are inspected regularly: By annual internal auditions and every 18 months by external independent inspectors. Doing this, our company proves that our laboratory complies in its complete processes (including order handling and reporting) with the normative.

All this proves to our clients:
Reliable results from a professional service provider.
