Male Lineage Y-Chromosome DNA Test
Compare male DNA through the paternal line
When do you need to do a Y-chromosome DNA test?
Our Y-Chromosome DNA test is designed to trace direct male lineage, offering insights into paternal relatives. Also known as a paternal lineage test or Y-STR comparison test, it can confirm a relationship within the direct male line. This test is particularly valuable in complex paternity scenarios when the potential father isn't available for testing. It can indirectly reveal connections to the possible father's brothers and other male relatives who share the same paternal lineage. Your report will be accessible in your secure online account just 5 business days after all samples reach the lab. Y-Chromosome DNA testing can address a wide range of relationship questions.

How a Male Lineage DNA Test Works
The Y-STR comparison DNA test relies on the stable inheritance of the Y chromosome from fathers to sons across generations. While the Y chromosome is exclusive to males, women can indirectly participate in a Chromosome DNA test to uncover information about their paternal relatives. To do so, they need to enlist the help of a close biological male relative—such as a father, brother, paternal uncle, or paternal grandfather—to provide a sample for comparison testing with their potential paternal relative or ancestor.
During a Y-chromosome DNA test, specific locations on the Y chromosome are scrutinized, generating a unique Y-STR profile for each male being tested. Males who share a paternal lineage will typically exhibit similar or identical Y-STR profiles, whereas those who are not related are likely to have distinct Y-STR profiles.
