When do you need a sibling test?
A sibling test can be seen as a closer relationship test. With this test, we examine whether two people are full siblings or half siblings (one parent in common) or not related. The test can also provide information about a possible father.
There are situations in which a possible father can no longer be tested, but his biological children can. If a possible father has children with, for example, two different women, a sibling test can be carried out between these children, which allows statements to be made about whether they have a common father.
Whose samples are needed for a sibling test?
Become same-sex siblings examined, an analysis of the X (sister test) or Y chromosomes (brother test) is carried out. We need a blood or saliva sample (oral swab) from the possible siblings.
- Brother test:
Men have one X chromosome and one Y chromosome. The Y chromosome makes a person male and is inherited from father to son. A brother test examines the Y chromosome, which the father only passes on to male offspring. In the case of two suspected brothers, an examination of the X chromosome can also be used to check whether they have the same mother.
- Sister test:
A sister test checks whether two women have the same father. For this, the possible father would have to have passed his X chromosome on to both daughters.
- Brother and sister:
For a sibling test between different genders, we may also need samples from the mother or mothers. In any case, regardless of the constellation, it is helpful if you contact us before choosing a test so that we can advise you. The possibilities of a relationship and the resulting probabilities of results are very diverse and should be discussed personally. We would be happy to advise you: 08092 8289 260
