How the DNA Sibling Test Works

A buccal mouth swab sample is collected from each potential sibling. At the laboratory, DNA is extracted from the cells and specific regions are amplified using PCR (polymerase chain reaction). The test analyzes 16 to 27 short tandem repeat (STR) regions — highly variable regions throughout the genome that provide an accurate way to confirm or refute biological sibling relationships. When a parent is available for testing, the DNA Paternity Test or DNA Maternity Test is recommended over the sibling test as it provides a more conclusive result. In situations where the alleged parents are missing or deceased, the DNA Sibling Test provides valuable insights into potential sibling connections.

Frequently Asked Questions

Can this test determine full siblings vs. half siblings?
Yes. The test determines whether the tested individuals are full siblings (sharing both biological parents), half siblings (sharing one biological parent), or not biologically related as siblings.

What if a parent is available for testing?
If either parent is available, the DNA Paternity Test or DNA Maternity Test is recommended over the DNA Sibling Test, as parental testing provides a more conclusive result.

Is there an age limit?
No. The DNA Sibling Test can be performed on individuals of any age, including newborns. If the patient is a minor, the legal guardian must sign the consent form.

How is the DNA sample collected?
DNA is collected by rubbing a brush gently inside the mouth against the cheek for 15 seconds. The collection is safe and painless.
