What is a legal male lineage DNA Test or Y-Chromosome DNA test (Also known as Y-STR comparison)?

The legal paternal relative (Y-STR) comparison test, also known as a paternal lineage test, can confirm a relationship to a distant relative. This DNA test is often used to provide additional evidence in difficult paternity situations in which the alleged father is not available for testing—indirectly, it can tell you whether or not a child is related to the alleged father’s brother(s) and other male relatives who share a common ‘paternal’ line.

The testing process is simple—the DNA samples are taken using a painless buccal (cheek) swab, and testing is completed in 5 business days. We can either send you a testing kit to collect your DNA samples at home, or if there are legal implications, we can use a Chain of Custody collection process where a trained professional near you will take your DNA samples.

Y-STR comparison vs. DNA testing for ancestry:
Unlike DNA tests for ancestry, the Y-STR comparison test provides scientific confirmation of more recent relationships—for example, if you have identified a possible relative from genealogy research and want to confirm your relationship. This Y-STR comparative analysis will tell you whether or not your Y-STRs are consistent, or not consistent, with the conclusion that you and the possible relative(s) may be related through a common male ancestor.

Comparison testing in paternity situations:
In a paternity situation where the alleged father is missing, Y-STR analysis cannot distinguish a specific relationship between males who belong to the same paternal line. However, it is useful for excluding males from an alleged biological relationship. For example, if a male child and his alleged uncle (alleged father’s full brother) are tested, their Y-STR profiles must match. If they do not, then the alleged uncle is excluded (not considered a biological uncle) and the alleged father is probably not the biological father.

Y Chromosome inheritance:
The Y-STR comparison DNA test is based on the fact that the Y chromosome is passed from father to son relatively unchanged through many generations. Because the Y chromosome follows the same father-to-son pattern much like surnames in Western culture, the test has also been referred to as a “Surname Test.”

Although the Y chromosome is only found in males, women can also indirectly participate in a Y-STR DNA test if they are interested in determining their paternal relatives. They would need to ask a biological male relative, such as a father, brother, paternal uncle, or paternal grandfather to contribute a sample for comparison testing with her potential paternal relative or ancestor.

In a Y-STR DNA test, specific locations on the Y chromosome are examined to generate a Y-STR profile for each male tested. Males who are related through their fathers will tend to have the same or similar Y-STR profiles, and males who are not related will likely have different Y-STR profiles.

There are many scenarios in which the Y-STR test may be used. To determine if this test will help you in your particular situation, please call us. One of our caring, knowledgeable DNA Experts will review the information you provide and guide you through the testing process.

Legal vs. at-home male lineage DNA test?

What to consider when selecting a DNA male lineage test?

Legal male lineage test:

Provides court-ready results that may be used to resolve child support disputes, custody disputes, probate issues and other legal matters. Samples are collected at one of EDC’s conveniently located certified collection facilities insuring proper chain of custody is maintained. A documented chain of custody is required for all tests that may be used for legal purposes.

At-home male lineage test:

Referred to as a non-legal male lineage test or at-home male lineage test. This male lineage test is used when you just need or want answers regarding genetic relationships. A pre-paid express envelope is provided so that you may expedite your DNA samples to the lab.

Price and affordability of a legal male lineage test?

Legal male lineage tests are more expensive than at-home male lineage tests as we ensure coordination of DNA collection and other features needed to issue a legal document. Therefore, if you only need the DNA male lineage test results to reveal the truth, then an affordable home male lineage test is the best choice for you. For additional peace of mind, EDC ensures that:
– The high-quality testing is strictly the same with every DNA test
– Industry-leading features include running every test twice (Duall Process) to ensure the highest accuracy
– Laboratory inspection excellence, proven by 18 perfect inspections of the most rigorous accrediting organisations

Possible reasons you might need a legal male lineage test?

When deciding between a peace-of-mind male lineage test and a legal male lineage test, it’s essential to consider what you need the results for. Too many new parents hurry and do an at-home male lineage test, thinking the results can be used for legal purposes—but the truth is courts won’t accept those results. Why? Because there’s no way to prove that the samples submitted for testing really belonged to the people whose names are on the report.
With a legal male lineage test, results are accepted by the court, because an independent, qualified third-party witness (also known as a DNA Collector) supervises the DNA collection process from beginning to end, including checking participant IDs, witnessing the handling of cheek swabs, completing paperwork, and mailing samples to the lab. That way, the court can be sure samples weren’t fraudulently tampered with. Here are the top 5 reasons why people need to get a legal, chain-of-custody test.

#1 Reason for a Legal Male Lineage Test: Child Custody and Child Support
#2 Reason for a Legal Male Lineage Test: Immigration
#3 Reason for a Legal Male Lineage Test: Inheritance Rights
#4 Reason for a Legal Male Lineage Test: Death Benefits
#5 Reason for a Legal Male Lineage Test: The Need to Know our Roots

What are the identity requirements for a legal male lineage test ?

When you go to your sample collection appointment, be sure to bring: Photo ID and birth certificate for people being tested.
At your appointment, we will: Take copies of your Photo ID / Birth certificate. Get thumbprints (or for babies we sometimes get footprints) of all people being tested. Take a ‘mug shot’ of all people being tested. Fill out consent forms and other paperwork.

Legal male lineage test results delay and how it looks?
