Y-Chromosome test
With a Y chromosome test you can determine whether 2 men are related. The Y chromosome is passed on from father to son and is virtually identical for subsequent generations. The Y chromosome can be tested in the lab using buccal mucosa. Simple and accessible.

A Y chromosome test as a paternity test
With a Y chromosome comparison test you can test whether there is a biological relationship between men. For example, between paternal grandfather and a grandson, or between a paternal uncle or cousin and a child. The Y chromosome is passed on from father to son and is virtually identical for subsequent generations. That means sons have the same Y chromosome as their father. But also that other male relatives in the male line have the same Y chromosome. Cousins, whose fathers are brother to each other, for example. This means that with a Y chromosome test you have options to determine paternity, without the father having to participate in a paternity test.
Because the Y chromosome is only passed on in the paternal line, women or girls cannot participate in a Y chromosome test.
Order Y chromosome test
You can simply order the Y chromosome test online. After we have received the payment from you, we will send you a package with the Y chromosome comparison test. The test comes in a neutral envelope and is therefore completely anonymous. You can immediately perform the Y chromosome test yourself.
This works as follows: you use a cotton swab to remove the buccal mucosa. Then send it to us in the enclosed envelope. A renowned laboratory examines the DNA samples and determines whether there is actually a family relationship between the men examined. We will send you the results by email or post. Completely anonymous of course.

Frequently Asked Questions
Does the mother have to participate in the Y chromosome test?
No that is not necessary. It’s not even possible. Y chromosomes are only passed from father to son.
Can a biological link between father and son be established if the father does not participate in the test?
Yes, the Y chromosome test is extremely suitable for this. The Y chromosome test can then be performed on the child and a male blood relative of the alleged father (for example, a paternal uncle, cousin or grandfather). The result of this DNA test will then indicate whether there is a relationship between the two men. The result does not indicate which relationship that is. But once the relationship has been established, you can also draw your conclusions about paternity.
Are there other DNA tests that establish paternity without the father participating?
Yes, other so-called ‘indirect’ DNA tests are possible. Think, for example, of the various (half) brother-sister tests, the uncle-aunt test and the grandparent test.
I need the results urgently, is that possible?
Yes, we can speed up the process for a small additional fee. Please do not hesitate to contact us and we will inform you about the possibilities.
What is a legally valid test?
With the exception of the prenatal paternity test, all DNA tests from paternity test.nu can also be ordered in the legally valid version. Legally valid means that you can submit the result in a legal procedure or lawsuit. For example, about family reunification, custody, alimony or an inheritance. The reliability of a legally valid test is the same as with an informative (peace of mind) test. Only the collection of the DNA sample is different and must meet certain guarantees.
Can I also use the results of a peace of mind test in a lawsuit?
Although the result of a peace of mind test is just as reliable as the result of a legally valid paternity test, we are not aware of any cases where the result of a peace of mind test has been accepted in legal proceedings. That’s because of the way the DNA is taken. If the parties take the DNA themselves, without the presence of an independent third party, the court or government agency cannot simply assume that the samples submitted actually come from the right people. And that the monsters have not been tampered with. So if you want to be sure that you can use the results in a lawsuit, choose the “legally valid” option when ordering.
