What is Y DNA Testing?
A Y DNA male lineage DNA test, or Y-STR test, is often the best option when the alleged siblings to be tested are males. The Y-STR test can conclusively determine if 2 or more males originate from some the same male line. Candidates for Y DNA testing include brothers, paternal cousins, grandfather/grandson, uncle/nephew and more, as long as all relationships are on the father’s side and through an unbroken male line.
It is important to note that the suspected alleged fathers must both come from the male line, such as being brother or cousins from the same paternal line. While the Y DNA test will not determine the exact biological relationship on the male side, it will however confirm or deny any existence of a biological relationship through the male side. In instances of paternal grandfather/grandson, or where full or half siblings are both males this is a more conclusive option especially when the mother(s) is not able or willing to participate.
With so many online offers for Y DNA tests, which should you choose? Most companies online resell the Y DNA order to the lowest bidder, who is often an out of country lab.

Our Y DNA testing delivers very conclusive test results that will answer the question – are the tested males from the same paternal line. The test focuses on the STR (Short Tandem Repeat) from the Y-chromosome passed from male to male. The Y-chromosome produces a variable sequence that is almost as unique as a fingerprint and is passed from father to son. This sequence will be virtually identical in an unbroken male lineage for generations. Subsequently, if the tested males are from the same paternal line, they will have matching Y-STR profiles.
The cost of Y DNA tests include analysis for 2 males. More test participants can be added if needed.
Our Y DNA test package comes complete with collection kit, DNA analysis and test results. Some companies advertise that you can make your own collection kit by using your own Q-tips®. However, we do not recommend this practice. There is a risk of multiple DNA samples being found on Q-tips® that are not sterile, or that may be handled by more than one person. Q-tips® you may have in your home could already have DNA from other sources on them. For this reason, we send a DNA collection kit containing sterile buccal swabs to you at no charge. We ship the kit to you via FREE USPS rushed delivery so you have your sterile medical swabs ready for use fast.

“In my opinion I am very satisfied. I have an adult daughter that’s 24 years old now that I did not know I had. The results came in very quickly, took a couple of days, and I am very pleased with this product. If I need it again, this is what I’ll get. I will definitely recommend this to anybody that needs to do a DNA test.”
