Grandparent DNA Testing

Grandparentage dna tests can be used to establish a biological relationship between an individual and one or more of their alleged grandparents.

A DNA profile for each individual is produced and the alleles observed at each Short Tandem Repeat (STR) marker are compared; biologically related individuals tend to have more DNA in common than unrelated individuals. Statistical analysis is performed taking into consideration the number of matches observed between the tested individuals and the frequency of the observed allele within the relevant population.

Why use our Grandparent DNA Test

The calculations performed result in a probability of relation, which are determined on the following scale:

  • POSITIVE: A result of 90-99.99% provides very strong evidence that a grandparent/grandchild relationship does exist.
  • NEGATIVE: A result of 0-10% is not supportive of a grandparent/grandchild relationship;
  • INCONCLUSIVE: Results falling within the 10-89.99% range are deemed to be inconclusive because it is not possible to determine conclusively if a biological relationship exists between the tested individuals.

An inconclusive Grandparent DNA Test result could be due to a low number of matching alleles between the tested individuals. Alternatively, the alleles that are shared between the tested parties could be extremely common within the relevant population. Analysis of additional STR markers may be recommended to improve the strength of the DNA evidence, however this will incur an additional cost and the result could still be inconclusive.

Grandparent DNA Testing is not as conclusive as paternity or maternity analysis and should be used when it is not possible to perform these other types of testing.
