More information about siblingship testing

What relationship does siblingship testing prove?

Siblingship DNA tests can be carried out to determine whether two people are full or half siblings (sisters or brothers).

  • Full siblings have the same mother and the same father.
  • Half siblings only share one biological parent.
Who needs to be tested?
  • The potential siblings
  • Any available parents – for example a shared mother, or if testing if two individuals are half siblings, both mothers.
How reliable are the results?

The likelihood of obtaining a conclusive result when undertaking a sibling test varies depending on which individuals are participating in the case.

When testing if two individuals are Full or Half Siblings:

  • Two Siblings and one shared parent – 96%
  • Two Siblings – 78%

When testing if two individuals are Half Siblings or are Unrelated:

  • Two Siblings and both mothers – 94%
  • Two Siblings one of their mothers – 86%
  • Two Siblings – 73%

Where a test comes back inconclusive, NorthGene will recommend which additional individuals may be required to provide a sample to improves the chances of gaining a conclusive result. There will be additional charges associated in these instances.
