Forensic Y-STR Testing Service - Non Standard/Special Samples
99.9999% accuracy guaranteed!
Our Informational Forensic Y-STR DNA Test Service using special samples, such as clothing or samples, will determine the likelihood that two males are related. The Y-STR (Paternal Lineage) DNA Test is a test to determine if 2 males share the same paternal lineage. The Y chromosome is passed from father to son relatively unchanged. By analyzing it we can determine if a male has a common ancestor.
Please note that a 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 an email with instructions on how to care for the forensic or Special Samples* (see instructions below). If selected we will send a collection kit for oral swabs and instructions on how to gather any additional oral swab 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 standard Forensic Y-STR DNA Test includes testing for:
2 biological males
It is important to note that this test ONLY WORKS on BIOLOGICAL MALES, not females, and only on males of the same paternal line. For example, testing an uncle on the mothers' side would not work.
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.The Y-STR (Paternal Lineage) DNA
