Forensic Home Sibling Testing Kit - Special Samples

99.9999% accuracy guaranteed!

Our Informational Forensic Sibling DNA Test using special samples, such as blood, hair, toothbrushes (recommended) samples, will determine the likelihood that a there is a biological relationship between 2 or more people. Our standard test includes testing for two persons.

Please note that Forensic Relationship Test cannot be done as a legal test due to chain of custody, if needed for a court case please consult an attorney.

When ordered we will send you instructions on how to care for the forensic or Special Samples* (see instructions below), oral swabs (if selected) and instructions on how to gather any additional samples needed (in cases where the blood or special sample is being tested against anothers’ DNA in which there is not a blood or special sample for), and a prepaid envelope to return the samples to our lab.

Please be aware that due to the nature of forensic testing a conclusive result is not guaranteed. An inconclusive result can be due to many factors. The sample can be too degraded to produce a profile, the sample can be contaminated and a DNA profile cannot be found, there may be no DNA found on the sample, etc. These, and many unlisted reasons, are not grounds for a retest or refund. Please see our Refund Policy for more info.

Our Sibling DNA Test compares the DNA of alleged siblings to determine one of three possible outcomes:

Full Siblings - Sibling share same parents. Around 50% shared genes.

Half Siblings - Sibling share one common parent.  Around 25% shared genes.

Unrelated - No common parents.

Our standard Sibling 2 Person DNA testing kit includes testing for:

• 1 Sibling

• 1 Potential Sibling

  • We always include a known parent in our Sibling DNA Testing at no extra cost. We strongly encourage the inclusion of a known parent to increase the accuracy of the results and to prevent inconclusive results.

Our laboratory is fully accredited and ISO certified and we test for 23 STR loci including gender ID markers to ensure the highest quality and accuracy of all DNA results.
