Relationship DNA Tests
Kinship DNA testing, often called DNA relationship testing, can be used to prove, or disprove, biological relationships between relatives. We provide many different types of kinship tests including Sibling DNA testing, which can be used to confirm whether alleged siblings are related or not. Relationship tests can also test other family members, such aunts/uncles, grandparents, and even tell if twins are identical or fraternal.
Court admissible relationship DNA tests can be done to indirectly prove paternity using siblings, grandparents, or aunts/uncles.

No. Relationship DNA testing is what is referred to as “private pay”. This is because DNA testing is not a medical test, even if requested by your medical provider.
DNA samples will degrade over time. We recommend sending all samples to our lab as soon as you can after collecting your samples. We can accept samples arriving at different times, and have a secure and safe method of storing samples once they arrive.
No. A person’s DNA is the same whether it is blood or cheek cells.
If the sample collected is a mouth swab there should be no effect on the outcome of the kinship testing. You should talk to one of our Genetic Consultants if you have recently had a blood transfusion or bone marrow transplant before ordering the test.
No. There is no age limit on collecting DNA. We have tested newborns right after birth, and individuals up to 99 years old.
All DNA samples are destroyed 30 days after testing. We never sell you DNA information, or personal information, and never use it for any other reason except the testing itself.
