Paternal Relative (Y-STR) Comparison Test
This test is used to support or disprove a direct paternal
between 2 or more male participants.
The paternal relative (Y-STR)
comparison test, also known as a paternal lineage test, can confirm your relationship to long-lost relatives
and paternal ancestors. This DNA test is also often used to provide additional evidence in difficult paternity cases in which
the alleged father is not available for testing—indirectly, it can tell whether or not a child is related to the alleged
father's brothers and other male relatives who share a common paternal line.
The testing process is simple—the
samples are taken using a painless buccal (cheek) swab, and testing is completed in 2–3 weeks. We can either send you
a testing kit to collect your DNA samples at home, or if your testing has legal implications, we can use a Chain of Custody
collection process where your samples will be taken by a trained professional in a laboratory or clinic.
