Kinship testing

  Attention! Changes due to the COVID-19 pandemic!

SIA GenEra changes the usual visiting procedure!

The laboratory accepts clients and patients in person strictly by prior appointment. To apply for a visit, write us or call us  26267833!

We recommend remote DNA testing, by ordering an off-site sampling kit in our online store. Go to the selected DNA test section and add it to the cart. Complete the purchase and we will send you a full sampling kit. Please note that the additional time required for sending the samples must be added to the total testing time.

Protect yourself and your loved ones! 

People choose kinship DNA testing for a variety of reasons. It can be curiosity about whether a particular person is your relative, or having to resolve internal family matters.

What kinship tests does SIA GenEra offer?

This guide will help you choose the right kinship DNA test, additional test, and kinship model. Use the icons in the lower-left corner of the presentation (PDF file for a download).

We currently offer an informative (the test has no legal force) two-person kinship test for the following kinship models:

  • Siblings;

  • Half-siblings;

  • Uncles, aunts — children of siblings;

  • Grandparents — grandchildren;

  • First-degree cousins;

  • Great-grandparents — great-grandchildren.

Why choose kinship testing at SIA GenEra?

SIA GenEra offers kinship testing using 22 autosomal DNA loci (with the possibility to add another 9 loci) or loci on sex chromosomes. This kinship DNA testing is based on Latvian allele frequency data, which yields the most accurate analysis results for clients of Latvian origin.

What do the results of the kinship test really mean?

Kinship DNA testing is essentially very similar to a paternity DNA test. In the analysis of kinship, the correct question is not “Are these persons related?” It would be correct to rephrase the question as follows: “Do the results of the DNA test indicate (provide additional information about) the existence of kinship?” This means that the result of the analysis will never be 100%, and a result of 0% will rarely be found (except for paternity, where there is a clear absence of paternity). Usually, the result of a kinship test, or the probability of kinship in %, will be somewhere between 0 and 100%. This is why the result of this analysis cannot be used as the sole evidence in confirming or refuting kinship. Other evidence and facts regarding the presence/absence of kinship should also be taken into account.

Since it is assumed that the initial probability (probability before the analysis) is, in the standard case, 50% (50% that the persons are related and 50% that the persons are unrelated), then theoretically any test result that is above 50% should be interpreted as supporting the existence of kinship and vice versa — any result below as 50% refuting kinship. Further interpretation of the result, for example, if the result is 70%, depends on the client because only he/she knows other facts, and evidence whether the analysed relationship is possible or not. SIA GenEra provides an interpretation in this matter; however, it should not be considered an absolute truth that confirms or refutes the existence of the kinship in question. In addition to the percentage result, other information is provided to help you understand the test result.


The results of a kinship DNA test are informative in nature and cannot be used to resolve legal matters unless the test is ordered by a court!
