Legal Y Chromosome DNA Test
Establish Male Lineage with Confidence—Legally and Accurately
The Legal Y Chromosome DNA Test is your trusted solution for confirming biological relationships between male relatives when a standard paternity test is not an option. Whether you’re verifying a father-son connection, testing brothers, or confirming an uncle-nephew or grandfather-grandson relationship, this test delivers court-admissible results with unmatched accuracy.
Processed by our AABB-accredited laboratory, the test strictly follows chain of custody protocols—making it fully compliant for use in legal situations like inheritance disputes, immigration, custody battles, and more.
A professional DNA collector will meet you at a certified facility to obtain painless cheek swabs. From there, your samples are expedited to our lab and analyzed using advanced Y-STR marker technology. Since the Y chromosome passes virtually unchanged from father to son, this test provides powerful evidence of a shared paternal line.
Your confidential results will be available in just 3-5 business days after the lab receives your samples, delivered securely through our encrypted online portal or by mail upon request.
