Determine the likelihood of being full siblings, half siblings, or not related

Discover the truth about familial relationships with our Home DNA Sibling Test. Ideal when the parents are not available for testing, this easy-to-use, confidential kit is designed for anyone seeking clarity on sibling relationships, directly from the comfort of your home.

With this easy-to-use home kit, you can collect a mouth swab quickly and discreetly in the privacy of your own home and send it to our laboratory for analysis. Your test results will be available for download from your secure online account within 1–2 business days of receipt at the lab.

Whenever the parent(s) in question are available for testing, either the DNA Paternity Test or DNA Maternity Test is recommended over the DNA Sibling Test. However, in situations where the alleged parents are missing or deceased, the DNA Sibling Test provides valuable insights into potential sibling connections.

DNA Sibling Test Methods

During a DNA Sibling Test, a buccal (mouth) swab sample is collected from the potential siblings. The sample contains cells, and most of the cells in our body contain a full set of genetic information in the form of DNA (deoxyribonucleic acid). A person's DNA represents a "genetic blueprint" and, like a fingerprint, it is unique to each individual.

At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction). Our test analyzes 16 to 27 specific regions called short tandem repeats (STRs). STRs are regions of DNA in which a short DNA sequence is repeated multiple times. They are found throughout the genome and are highly variable, providing an accurate way to confirm or refute biological relationships.
