Paternal Lineage DNA Testing
Fast, Accurate, and Confidential At-Home DNA Testing
A home paternal lineage DNA test, also known as a Y-STR test, is designed to determine whether two or more males share a common paternal line. This test analyzes DNA passed down virtually unchanged from father to son, making it a powerful tool for exploring male-line relationships.
Our home Y-STR DNA tests are accurate, affordable, and discreet, providing clarity when traditional paternity or relationship testing is not appropriate.

What Is a Y-STR DNA Test?
A Y-STR DNA test examines specific markers on the Y chromosome, which is passed exclusively from father to son. Because females do not carry a Y chromosome, this test is used only for male participants.
Y-STR testing can help determine whether two males share a paternal ancestor but cannot determine the exact relationship (such as father, uncle, or cousin) without additional context or testing.
When Is Home Paternal Lineage DNA Testing Used?
Home Y-STR DNA testing is commonly used to:
Confirm whether two men share the same paternal lineage
Explore family history or genealogy
Support surname or ancestry research
Help narrow possible biological fathers within the same paternal line
Y-STR testing is for personal knowledge and is not intended for legal use.

Sterile cheek swabs for each participant
Step-by-step sample collection instructions

Understanding Your Y-STR DNA Test Results
Y-STR DNA test results will indicate whether the tested males share the same paternal lineage:
Match – The tested males share a common paternal ancestor
No Match – The tested males do not share the same paternal line
Because Y-STR markers are inherited together, identical results suggest a shared male ancestor at some point in the paternal line.

FAQs About Male Lineage DNA Tests
Below, we’ve answered some common questions about our Y-chromosome DNA test.
-
Results from a home DNA test cannot be used as proof of paternity for legal reasons such as child support, custody, Social Security, etc. At-home results cannot be used because the DNA sample is collected by the test participants themselves. This means chain-of-custody protocol cannot be followed, and identities of tested parties cannot be independently verified.
-
Yes. Results for a home paternity test are just as accurate as they are for a legal paternity test. In fact, once DNA samples arrive at the lab, the process for testing is exactly the same for a home test as it is for a legal one. You can be certain your results for a home paternity test are accurate for the samples we are provided, but remember the results are just for peace of mind and personal knowledge only. If you need results for court or think you may in the future, call us.
-
Y-chromosome DNA testing is highly accurate for tracing paternal lineage and confirming biological relationships along the male line. The precision of our testing methods ensures reliable results.
-
Y-DNA testing is invaluable for anyone interested in tracing their paternal lineage, confirming paternity, or gaining insights into their genetic heritage.
-
Markers, or Short Tandem Repeats (STRs), are specific sequences on the Y chromosome that are analyzed in Y-DNA testing to determine genetic relationships.
-
No, Y-STR testing targets the Y chromosome on males. Females do not have a Y chromosome.
