DNA grandparent testing

Grandparent DNA tests can be used to establish a biological relationship between an individual and one or both of their alleged grandparents.

A DNA profile for each individual is produced and the DNA markers are compared; biologically-related individuals tend to have more DNA in common than unrelated individuals. Our grandparent tests look at 24 DNA markers and examine the child’s DNA and identify which half is inherited from the grandparents.

Statistical analysis is performed taking into consideration the number of matches observed between the tested individuals and the frequency of the observed marker within the relevant population. The calculations performed result in a probability of relatedness:

  • SUPPORTIVE: A result of 9099% provides very strong evidence that a grandparent/grandchild relationship does exist
  • NOT-SUPPORTIVE: A result of 010% is not supportive of a grandparent/grandchild relationship
  • INCONCLUSIVE: Results falling within the 1099% 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 result could be due to a low number of matching DNA markers shared between the tested individuals. Alternatively, the markers that are shared between the tested parties could be extremely common within the relevant population.

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

A guaranteed result or your money back

We understand that the reason you have ordered a DNA test is to get an answer. However, not all tests are conclusive, and therefore you may not get the decisive answer you are looking for. 

It is the testing industry’s best kept secret that for most laboratories, grandparent DNA testing can be up to 40% inconclusive. In other words, four people out of every 10 do not get the result they have paid for. 

Our award-winning DNA laboratory has been able to reduce the inconclusive rate down to 23%.

This is a better outcome but is still not acceptable to us. That’s why AlphaBiolabs has launched a guaranteed result or your money back promise. We will refund the price of your test, guaranteed, if you use our service and don’t get a conclusive result.
