Siblings DNA Test in Tbilisi
The Molecular Genetics Center «DTL» offers genetic DNA testing to establish sibling relationships (full or half-siblings). Our DNA siblings test determines familial ties (kinship) between close and distant potential relatives.
We use a large number of unique autosomal markers, as well as Y-chromosome or mtDNA testing, depending on each specific case. Different situations require different methodologies. In the past, DNA analysis to determine kinship between siblings often required additional participants for accuracy. However, our laboratory employs the most advanced DNA research methods and protocols, allowing us to achieve the highest accuracy without the need for additional participants.

How to do a Sibling DNA Test in Tbilisi
The process of taking DNA samples from participants is completely painless and takes about 4-6 minutes. Often, the DNA sample used for this genetic test is a buccal swab taken with a cotton swab (cheek epithelial cell collection), also known as a saliva test (standard DNA sample).
If it is not possible to take a standard sample, alternative samples can be used (non-standard). These include blood, paraffin blocks, cigarette butts, hair, various biological stains and fluids, nails, cutlery, and more. For a detailed list and descriptions click here.
