Siblings DNA Test
|Sibling DNA tests determine whether two alleged siblings are in fact biological half siblings or full siblings. homeDNAdirect Ireland recommends this test when it is not possible to do a paternity DNA test or Maternity DNA test. The cost of sibling testing starts from €329.
We strongly suggest including the sample of a known mother to provide stronger results.
A DNA sibling test is used to determine whether siblings share a biological parent without in fact testing the DNA of the parent in question. This means that a sibling test is done without the DNA of parent.
The objective of a DNA siblings test is to indicate whether siblings are full siblings, half siblings or unrelated.
We offer 4 types of siblings test. We recommend you access the links provided to find out which of the following tests is more suitable to your requirements:
Please note that X chromosome testing can still be done in cases where two females share the same mother. However, in such a case, the test will only be conclusive if the mother’s DNA is tested alongside that of the other females taking part.
