Full brother sister DNA test
At Vaderschapstest.nu you can order various kinship tests. Likewise a half brother and sister test and a full brother and sister test. You can order this test if you would like to know whether you and your brother or sister have the same biological parents. If you do not have the same mother or if you are not sure whether you and your brother or sister have the same mother and want to know whether you have the same father, you can also choose to have a half-brother-sister test taken.
Half brother sister DNA test
A half-sibling test allows you to test if you suspect that you and another person have a common biological parent. Sometimes it is recommended that one or more mothers participate in the test.

Frequently Asked Questions
Does the biological parent also have to participate in this DNA test?
The test can in principle be performed without parents. But if a biological parent is known who wants to participate, this will of course improve the accuracy of the test.
What is the difference between a full sibling test, a half sibling test and a combined half and full sibling test?
You take a full brother/sister test if you are sure that you have the same biological mother, but want to know whether you also have the same biological father.
You take a half-brother/half-sister test if you already know that you do not have the same biological mother, but want to know whether you do have the same biological father. Due to the complexity of this test, we recommend that at least one, but no less than two biological mothers be tested. The laboratory then excludes the DNA material passed from the mother to the children, allowing it to focus fully on any similarities in the DNA of the alleged father and the child.
You do a combined half and full brother/sister test if you do not have the same biological mother, or if you are in doubt about this and you want to know whether you have the same mother and father.
Who can participate in this DNA test?
(Half)brothers and (half)sisters in different combinations. The test is therefore suitable for 2 or more alleged (half) brothers, 2 or more alleged (half) sisters and different combinations of (half) brothers and (half) sisters. It helps for accuracy if the known biological parents also participate.
Are there other DNA tests that establish paternity without the father participating?
Yes, other so-called ‘indirect’ DNA tests are possible. For example, think of the Y-chromosome test, the 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.
