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:

  • STR testing: done between male and female siblings.
  • X chromosome testing: done when two sisters from different mothers want to establish if they share the same father.
  • Y chromosome testing: carried out two brothers wish to know if they share the same father;
  • MtDNA testing: if individuals want to know if they share the same maternal line.
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.
