Sibling DNA Testing from £99.00

Today we can use DNA technology to establish whether or not a brother and a sister have the same father or the same father and mother.

AlphaBiolabs Sibling DNA testing has an accuracy rate of 100%. We ask for the inclusion of the mother’s DNA  samples in this testing procedure as this usually increases the accuracy rate. We use statistical analysis to evaluate the amount of DNA shared between the individuals tested to deduce a biological relationship. For example, full siblings usually have more DNA in common than half-siblings, while half siblings normally share more DNA than unrelated persons.

Our sibling DNA test requires the participation of two alleged siblings.

Why is this sibling DNA test different?

Unlike a paternity test which will always provide a conclusive result, sibling DNA testing is different. When a sibling test is conducted, the DNA laboratory will determine the genetic profiles of the alleged siblings.

Based on the genetic material shared by each sibling, a sibling DNA index or likelihood ratio is calculated to determine the most likely relationship.

A likelihood of greater than 10 supports that the tested individuals are related as siblings, either full or half; whereas a likelihood of less than 0.1 does not support this. A likelihood which falls between 0.1 and 10 is considered inconclusive, which means a relationship cannot be determined, based on the statistical probability obtained from the analysis.

The higher the value of the sibling DNA index, the greater the likelihood that the two individuals are true biological siblings. It is possible to analyse two individuals to determine that they are more likely to share only two common parents versus one common parent (i.e. They are full siblings sharing a mother and father) or that it is more likely that they have one parent in common versus them being unrelated (i.e. That they are half-siblings, with s single parent in common).

What is a Sibling?

  • Individuals are classed as full siblings when both biological parents are the same.
  • Half siblings are individuals who share only one biological parent, either the mother or the father.
