When testing for sibling relationships, the DNA laboratory will determine the genetic profile of the possible siblings and will calculate a sibling DNA index or likelihood ratio. Full siblings usually have more DNA in common than half-siblings, while half siblings normally share more DNA than unrelated persons. Unfortunately, It is the industry’s best kept secret that for most laboratories but sibling testing can be up to 40% inconclusive. This means that four people in every 10 do not get the result they have paid for. At our award-winning DNA laboratory, we have reduced this inconclusive rate to 24%, meaning that only around one in four people do not get a definitive outcome.
