Grandparent DNA tests can be used to establish a biological relationship between an individual and one or more of their alleged grandparents.
One of the main reasons why a grandparent DNA test is performed is when a child’s alleged father is unavailable for paternity testing and the child’s grandparents want to know whether the child is truly related to them.
In a grandparent test, a DNA profile is produced for each individual taking part in the test. Since a child inherits half of his or her genetic profile from each biological parent, when one or more of a child’s parents is unavailable for testing, we can look to the grandparents to determine if they contributed DNA to the child’s genetic profile.
DNA grandparent testing is not as conclusive as paternity or maternity analysis and should only be used when it is not possible to perform these other types of testing.
People who are related usually share more genetic markers than people who are unrelated and an inconclusive DNA grandparent test result could be due to a low number of matching DNA markers between the tested individuals. Alternatively, the markers that are shared between the tested parties could be extremely common within the relevant population.
At London Medical Testing 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 a decisive answer to your question.
It is the industry’s best kept secret that for most laboratories, grandparent 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 been able to reduce this inconclusive rate to 23%, meaning that only around one in four people do not get an answer to their question.
This is still not acceptable at AlphaBiolabs and with this in mind we have launched our guaranteed result or your money back promise. For the small number of customers who order a Grandparent DNA Test and do not get a conclusive result, we will refund the price of the test, guaranteed. Please note, all relationship DNA tests bought via third party retailers are not included in this guarantee.
