The traditional DNA-based grandparent–grandchild test makes it possible to clarify the paternal lineage and determine whether the tested grandparents are truly the biological grandparents of the child. The test is more accurate if DNA samples from both paternal grandparents – the grandfather and the grandmother – are available. In the case of a male grandchild, the inclusion of the grandfather’s DNA sample alone is sufficient to achieve reliable results.
Sample collection is painless and performed using buccal epithelial cells, which can be collected at home by the client. Results are available within 10–12 days, providing accurate and reliable answers regarding the biological relationship.
The grandparent–grandchild DNA test offered by DNS Központ is a specialized genetic analysis that enables the precise determination of biological relationship between a grandparent and a grandchild. This test is typically recommended when the alleged biological parent (mother or father) is not available, allowing the biological connection to be confirmed indirectly.
How does the grandparent–grandchild DNA test work?
During the test, DNA samples from the grandparent(s) and the grandchild are compared. Sample collection is simple, painless, and discreet, using buccal epithelial cells (“saliva sample”). In our laboratory, genetic markers found in the DNA of the grandparent(s) are compared with those of the grandchild, and statistical analysis is used to determine the probability of a biological relationship.
How accurate is the test?
The grandparent–grandchild DNA test determines biological relatedness with high accuracy. Although it requires a more complex analysis than direct parent-child testing, the relationship can still be confirmed with a reliability of at least 99%, or excluded with 100% certainty if no biological connection exists.
When is a grandparent–grandchild DNA test needed?
- When the alleged biological parent is unavailable or deceased.
- In cases of family disputes, inheritance matters, family reunification, or immigration procedures.
- When biological relationship must be proven for legal purposes.
