Variants of DNA sibling-testing


Brother test

We can use the analysis of the Y chromosome to determine a biological father. But since it is the same Y-Chromosome that is passed through the complete male line caution is advised. If another male relative is a putative biological  father, please inform us beforehand.

Sister test

If the mother wants to take part in the test we can conduct a simple maternity test.

If she cannot be part of the testing we can analyse the entire maternal line by examining mitochondrial DNA. If 2 women are certain to share a biological mother, the joint biological father can be determined by an X chromosome test. If the mother takes part in the test the results become more accurate.

Brother-Sister Test

A sibling test between participants of different sexes can be complicated. We recommend involving even more relatives in the test. Please discuss the options with us in advance.

With this test we determine full or half siblings.


Please note: Due to law regulations a witnessed sampling is mandatory for every genetic analysis.



How long does it take to get the results?

It may take us up to 1 week or more to establish a result. Depending on your question the inclusion of different relatives can be helpful. Please contact us before you send your samples. We can discuss whose samples would be helpfulwith your specific relationship test. (for more background info please read on: FAQ-relationship testing)

Accuracy / how reliable is the result?
We confirm a relationship between the participants with a probability of up to 99,99999%. An exclusion will be given with 100%
