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.

FAQs About Relationship DNA Testing

What the difference between a legal test and a home DNA test?

A legal test is court admissible. The identity of each individual tested is varified and the chain of custody is tracked. A third party performs the collection. Results are delivered within 3 business days. Informational or private test is for your own peace of mind and is not court admissible. You can perform the collections in your own home. The results are delivered in 1 – 2 business days.

Is DNA kinship testing covered by insurance?

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.

Do DNA samples ever expire?

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.

Is a blood sample more accurate than a mouth swab?

No. A person’s DNA is the same whether it is blood or cheek cells.

Will an operation or medical condition affect DNA results?

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.

Is there a minimum age for a child to do a DNA test?

No. There is no age limit on collecting DNA. We have tested newborns right after birth, and individuals up to 99 years old.

What happens to my DNA after the test is completed?

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.
